-/**
- * {@icuenhanced java.text.DecimalFormat}.{@icu _usage_}
- *
- * <code>DecimalFormat</code> is a concrete subclass of {@link NumberFormat} that formats
- * decimal numbers. It has a variety of features designed to make it possible to parse and
- * format numbers in any locale, including support for Western, Arabic, or Indic digits.
- * It also supports different flavors of numbers, including integers ("123"), fixed-point
- * numbers ("123.4"), scientific notation ("1.23E4"), percentages ("12%"), and currency
- * amounts ("$123.00", "USD123.00", "123.00 US dollars"). All of these flavors can be
- * easily localized.
- *
- * <p>To obtain a {@link NumberFormat} for a specific locale (including the default
- * locale) call one of <code>NumberFormat</code>'s factory methods such as {@link
- * NumberFormat#getInstance}. Do not call the <code>DecimalFormat</code> constructors
- * directly, unless you know what you are doing, since the {@link NumberFormat} factory
- * methods may return subclasses other than <code>DecimalFormat</code>. If you need to
- * customize the format object, do something like this:
- *
- * <blockquote><pre>
- * NumberFormat f = NumberFormat.getInstance(loc);
- * if (f instanceof DecimalFormat) {
- * ((DecimalFormat) f).setDecimalSeparatorAlwaysShown(true);
- * }</pre></blockquote>
- *
- * <p><strong>Example Usage</strong>
- *
- * Print out a number using the localized number, currency, and percent
- * format for each locale.
- *
- * <blockquote><pre>
- * Locale[] locales = NumberFormat.getAvailableLocales();
- * double myNumber = -1234.56;
- * NumberFormat format;
- * for (int j=0; j<3; ++j) {
- * System.out.println("FORMAT");
- * for (int i = 0; i < locales.length; ++i) {
- * if (locales[i].getCountry().length() == 0) {
- * // Skip language-only locales
- * continue;
- * }
- * System.out.print(locales[i].getDisplayName());
- * switch (j) {
- * case 0:
- * format = NumberFormat.getInstance(locales[i]); break;
- * case 1:
- * format = NumberFormat.getCurrencyInstance(locales[i]); break;
- * default:
- * format = NumberFormat.getPercentInstance(locales[i]); break;
- * }
- * try {
- * // Assume format is a DecimalFormat
- * System.out.print(": " + ((DecimalFormat) format).toPattern()
- * + " -> " + form.format(myNumber));
- * } catch (Exception e) {}
- * try {
- * System.out.println(" -> " + format.parse(form.format(myNumber)));
- * } catch (ParseException e) {}
- * }
- * }</pre></blockquote>
- *
- * <p>Another example use getInstance(style).<br>
- * Print out a number using the localized number, currency, percent,
- * scientific, integer, iso currency, and plural currency format for each locale.
- *
- * <blockquote><pre>
- * ULocale locale = new ULocale("en_US");
- * double myNumber = 1234.56;
- * for (int j=NumberFormat.NUMBERSTYLE; j<=NumberFormat.PLURALCURRENCYSTYLE; ++j) {
- * NumberFormat format = NumberFormat.getInstance(locale, j);
- * try {
- * // Assume format is a DecimalFormat
- * System.out.print(": " + ((DecimalFormat) format).toPattern()
- * + " -> " + form.format(myNumber));
- * } catch (Exception e) {}
- * try {
- * System.out.println(" -> " + format.parse(form.format(myNumber)));
- * } catch (ParseException e) {}
- * }</pre></blockquote>
- *
- * <h3>Patterns</h3>
- *
- * <p>A <code>DecimalFormat</code> consists of a <em>pattern</em> and a set of
- * <em>symbols</em>. The pattern may be set directly using {@link #applyPattern}, or
- * indirectly using other API methods which manipulate aspects of the pattern, such as the
- * minimum number of integer digits. The symbols are stored in a {@link
- * DecimalFormatSymbols} object. When using the {@link NumberFormat} factory methods, the
- * pattern and symbols are read from ICU's locale data.
- *
- * <h4>Special Pattern Characters</h4>
- *
- * <p>Many characters in a pattern are taken literally; they are matched during parsing
- * and output unchanged during formatting. Special characters, on the other hand, stand
- * for other characters, strings, or classes of characters. For example, the '#'
- * character is replaced by a localized digit. Often the replacement character is the
- * same as the pattern character; in the U.S. locale, the ',' grouping character is
- * replaced by ','. However, the replacement is still happening, and if the symbols are
- * modified, the grouping character changes. Some special characters affect the behavior
- * of the formatter by their presence; for example, if the percent character is seen, then
- * the value is multiplied by 100 before being displayed.
- *
- * <p>To insert a special character in a pattern as a literal, that is, without any
- * special meaning, the character must be quoted. There are some exceptions to this which
- * are noted below.
- *
- * <p>The characters listed here are used in non-localized patterns. Localized patterns
- * use the corresponding characters taken from this formatter's {@link
- * DecimalFormatSymbols} object instead, and these characters lose their special status.
- * Two exceptions are the currency sign and quote, which are not localized.

- * </blockquote>
- *
- * <p>A <code>DecimalFormat</code> pattern contains a postive and negative subpattern, for
- * example, "#,##0.00;(#,##0.00)". Each subpattern has a prefix, a numeric part, and a
- * suffix. If there is no explicit negative subpattern, the negative subpattern is the
- * localized minus sign prefixed to the positive subpattern. That is, "0.00" alone is
- * equivalent to "0.00;-0.00". If there is an explicit negative subpattern, it serves
- * only to specify the negative prefix and suffix; the number of digits, minimal digits,
- * and other characteristics are ignored in the negative subpattern. That means that
- * "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)".
- *
- * <p>The prefixes, suffixes, and various symbols used for infinity, digits, thousands
- * separators, decimal separators, etc. may be set to arbitrary values, and they will
- * appear properly during formatting. However, care must be taken that the symbols and
- * strings do not conflict, or parsing will be unreliable. For example, either the
- * positive and negative prefixes or the suffixes must be distinct for {@link #parse} to
- * be able to distinguish positive from negative values. Another example is that the
- * decimal separator and thousands separator should be distinct characters, or parsing
- * will be impossible.
- *
- * <p>The <em>grouping separator</em> is a character that separates clusters of integer
- * digits to make large numbers more legible. It commonly used for thousands, but in some
- * locales it separates ten-thousands. The <em>grouping size</em> is the number of digits
- * between the grouping separators, such as 3 for "100,000,000" or 4 for "1 0000
- * 0000". There are actually two different grouping sizes: One used for the least
- * significant integer digits, the <em>primary grouping size</em>, and one used for all
- * others, the <em>secondary grouping size</em>. In most locales these are the same, but
- * sometimes they are different. For example, if the primary grouping interval is 3, and
- * the secondary is 2, then this corresponds to the pattern "#,##,##0", and the number
- * 123456789 is formatted as "12,34,56,789". If a pattern contains multiple grouping
- * separators, the interval between the last one and the end of the integer defines the
- * primary grouping size, and the interval between the last two defines the secondary
- * grouping size. All others are ignored, so "#,##,###,####" == "###,###,####" ==
- * "##,#,###,####".
- *
- * <p>Illegal patterns, such as "#.#.#" or "#.###,###", will cause
- * <code>DecimalFormat</code> to throw an {@link IllegalArgumentException} with a message
- * that describes the problem.
- *
- * <h4>Pattern BNF</h4>
- *
- * <pre>
- * pattern := subpattern (';' subpattern)?
- * subpattern := prefix? number exponent? suffix?
- * number := (integer ('.' fraction)?) | sigDigits
- * prefix := '\u0000'..'\uFFFD' - specialCharacters
- * suffix := '\u0000'..'\uFFFD' - specialCharacters
- * integer := '#'* '0'* '0'
- * fraction := '0'* '#'*
- * sigDigits := '#'* '@' '@'* '#'*
- * exponent := 'E' '+'? '0'* '0'
- * padSpec := '*' padChar
- * padChar := '\u0000'..'\uFFFD' - quote
- *  
- * Notation:
- * X* 0 or more instances of X
- * X? 0 or 1 instances of X
- * X|Y either X or Y
- * C..D any character from C up to D, inclusive
- * S-T characters in S, except those in T
- * </pre>
- * The first subpattern is for positive numbers. The second (optional)
- * subpattern is for negative numbers.
- *
- * <p>Not indicated in the BNF syntax above:
- *
- * <ul>
- *
- * <li>The grouping separator ',' can occur inside the integer and sigDigits
- * elements, between any two pattern characters of that element, as long as the integer or
- * sigDigits element is not followed by the exponent element.
- *
- * <li>Two grouping intervals are recognized: That between the decimal point and the first
- * grouping symbol, and that between the first and second grouping symbols. These
- * intervals are identical in most locales, but in some locales they differ. For example,
- * the pattern "#,##,###" formats the number 123456789 as
- * "12,34,56,789".
- *
- * <li>The pad specifier <code>padSpec</code> may appear before the prefix, after the
- * prefix, before the suffix, after the suffix, or not at all.
- *
- * <li>In place of '0', the digits '1' through '9' may be used to indicate a rounding
- * increment.
- *
- * </ul>
- *
- * <h4>Parsing</h4>
- *
- * <p><code>DecimalFormat</code> parses all Unicode characters that represent decimal
- * digits, as defined by {@link UCharacter#digit}. In addition,
- * <code>DecimalFormat</code> also recognizes as digits the ten consecutive characters
- * starting with the localized zero digit defined in the {@link DecimalFormatSymbols}
- * object. During formatting, the {@link DecimalFormatSymbols}-based digits are output.
- *
- * <p>During parsing, grouping separators are ignored.
- *
- * <p>For currency parsing, the formatter is able to parse every currency style formats no
- * matter which style the formatter is constructed with. For example, a formatter
- * instance gotten from NumberFormat.getInstance(ULocale, NumberFormat.CURRENCYSTYLE) can
- * parse formats such as "USD1.00" and "3.00 US dollars".
- *
- * <p>If {@link #parse(String, ParsePosition)} fails to parse a string, it returns
- * <code>null</code> and leaves the parse position unchanged. The convenience method
- * {@link #parse(String)} indicates parse failure by throwing a {@link
- * java.text.ParseException}.
- *
- * <p>Parsing an extremely large or small absolute value (such as 1.0E10000 or 1.0E-10000)
- * requires huge memory allocation for representing the parsed number. Such input may expose
- * a risk of DoS attacks. To prevent huge memory allocation triggered by such inputs,
- * <code>DecimalFormat</code> internally limits of maximum decimal digits to be 1000. Thus,
- * an input string resulting more than 1000 digits in plain decimal representation (non-exponent)
- * will be treated as either overflow (positive/negative infinite) or underflow (+0.0/-0.0).
- *
- * <h4>Formatting</h4>
- *
- * <p>Formatting is guided by several parameters, all of which can be specified either
- * using a pattern or using the API. The following description applies to formats that do
- * not use <a href="#sci">scientific notation</a> or <a href="#sigdig">significant
- * digits</a>.
- *
- * <ul><li>If the number of actual integer digits exceeds the <em>maximum integer
- * digits</em>, then only the least significant digits are shown. For example, 1997 is
- * formatted as "97" if the maximum integer digits is set to 2.
- *
- * <li>If the number of actual integer digits is less than the <em>minimum integer
- * digits</em>, then leading zeros are added. For example, 1997 is formatted as "01997"
- * if the minimum integer digits is set to 5.
- *
- * <li>If the number of actual fraction digits exceeds the <em>maximum fraction
- * digits</em>, then half-even rounding it performed to the maximum fraction digits. For
- * example, 0.125 is formatted as "0.12" if the maximum fraction digits is 2. This
- * behavior can be changed by specifying a rounding increment and a rounding mode.
- *
- * <li>If the number of actual fraction digits is less than the <em>minimum fraction
- * digits</em>, then trailing zeros are added. For example, 0.125 is formatted as
- * "0.1250" if the mimimum fraction digits is set to 4.
- *
- * <li>Trailing fractional zeros are not displayed if they occur <em>j</em> positions
- * after the decimal, where <em>j</em> is less than the maximum fraction digits. For
- * example, 0.10004 is formatted as "0.1" if the maximum fraction digits is four or less.
- * </ul>
- *
- * <p><strong>Special Values</strong>
- *
- * <p><code>NaN</code> is represented as a single character, typically
- * <code>\uFFFD</code>. This character is determined by the {@link
- * DecimalFormatSymbols} object. This is the only value for which the prefixes and
- * suffixes are not used.
- *
- * <p>Infinity is represented as a single character, typically <code>\u221E</code>,
- * with the positive or negative prefixes and suffixes applied. The infinity character is
- * determined by the {@link DecimalFormatSymbols} object.
- *
- * <h4><a name="sci">Scientific Notation</a></h4>
- *
- * <p>Numbers in scientific notation are expressed as the product of a mantissa and a
- * power of ten, for example, 1234 can be expressed as 1.234 x 10<sup>3</sup>. The
- * mantissa is typically in the half-open interval [1.0, 10.0) or sometimes [0.0, 1.0),
- * but it need not be. <code>DecimalFormat</code> supports arbitrary mantissas.
- * <code>DecimalFormat</code> can be instructed to use scientific notation through the API
- * or through the pattern. In a pattern, the exponent character immediately followed by
- * one or more digit characters indicates scientific notation. Example: "0.###E0" formats
- * the number 1234 as "1.234E3".
- *
- * <ul>
- *
- * <li>The number of digit characters after the exponent character gives the minimum
- * exponent digit count. There is no maximum. Negative exponents are formatted using the
- * localized minus sign, <em>not</em> the prefix and suffix from the pattern. This allows
- * patterns such as "0.###E0 m/s". To prefix positive exponents with a localized plus
- * sign, specify '+' between the exponent and the digits: "0.###E+0" will produce formats
- * "1E+1", "1E+0", "1E-1", etc. (In localized patterns, use the localized plus sign
- * rather than '+'.)
- *
- * <li>The minimum number of integer digits is achieved by adjusting the exponent.
- * Example: 0.00123 formatted with "00.###E0" yields "12.3E-4". This only happens if
- * there is no maximum number of integer digits. If there is a maximum, then the minimum
- * number of integer digits is fixed at one.
- *
- * <li>The maximum number of integer digits, if present, specifies the exponent grouping.
- * The most common use of this is to generate <em>engineering notation</em>, in which the
- * exponent is a multiple of three, e.g., "##0.###E0". The number 12345 is formatted
- * using "##0.####E0" as "12.345E3".
- *
- * <li>When using scientific notation, the formatter controls the digit counts using
- * significant digits logic. The maximum number of significant digits limits the total
- * number of integer and fraction digits that will be shown in the mantissa; it does not
- * affect parsing. For example, 12345 formatted with "##0.##E0" is "12.3E3". See the
- * section on significant digits for more details.
- *
- * <li>The number of significant digits shown is determined as follows: If
- * areSignificantDigitsUsed() returns false, then the minimum number of significant digits
- * shown is one, and the maximum number of significant digits shown is the sum of the
- * <em>minimum integer</em> and <em>maximum fraction</em> digits, and is unaffected by the
- * maximum integer digits. If this sum is zero, then all significant digits are shown.
- * If areSignificantDigitsUsed() returns true, then the significant digit counts are
- * specified by getMinimumSignificantDigits() and getMaximumSignificantDigits(). In this
- * case, the number of integer digits is fixed at one, and there is no exponent grouping.
- *
- * <li>Exponential patterns may not contain grouping separators.
- *
- * </ul>
- *
- * <h4><a name="sigdig">Significant Digits</a></h4>
- *
- * <code>DecimalFormat</code> has two ways of controlling how many digits are shows: (a)
- * significant digits counts, or (b) integer and fraction digit counts. Integer and
- * fraction digit counts are described above. When a formatter is using significant
- * digits counts, the number of integer and fraction digits is not specified directly, and
- * the formatter settings for these counts are ignored. Instead, the formatter uses
- * however many integer and fraction digits are required to display the specified number
- * of significant digits. Examples:
- *
- * <blockquote>
- * <table border=0 cellspacing=3 cellpadding=0>
- * <tr style="background-color: #ccccff">
- * <th align=left>Pattern
- * <th align=left>Minimum significant digits
- * <th align=left>Maximum significant digits
- * <th align=left>Number
- * <th align=left>Output of format()
- * <tr style="vertical-align: top;">
- * <td><code>@@@</code>
- * <td>3
- * <td>3
- * <td>12345
- * <td><code>12300</code>
- * <tr style="vertical-align: top; background-color: #eeeeff;">
- * <td><code>@@@</code>
- * <td>3
- * <td>3
- * <td>0.12345
- * <td><code>0.123</code>
- * <tr style="vertical-align: top;">
- * <td><code>@@##</code>
- * <td>2
- * <td>4
- * <td>3.14159
- * <td><code>3.142</code>
- * <tr style="vertical-align: top; background-color: #eeeeff;">
- * <td><code>@@##</code>
- * <td>2
- * <td>4
- * <td>1.23004
- * <td><code>1.23</code>
- * </table>
- * </blockquote>
- *
- * <ul>
- *
- * <li>Significant digit counts may be expressed using patterns that specify a minimum and
- * maximum number of significant digits. These are indicated by the <code>'@'</code> and
- * <code>'#'</code> characters. The minimum number of significant digits is the number of
- * <code>'@'</code> characters. The maximum number of significant digits is the number of
- * <code>'@'</code> characters plus the number of <code>'#'</code> characters following on
- * the right. For example, the pattern <code>"@@@"</code> indicates exactly 3 significant
- * digits. The pattern <code>"@##"</code> indicates from 1 to 3 significant digits.
- * Trailing zero digits to the right of the decimal separator are suppressed after the
- * minimum number of significant digits have been shown. For example, the pattern
- * <code>"@##"</code> formats the number 0.1203 as <code>"0.12"</code>.
- *
- * <li>If a pattern uses significant digits, it may not contain a decimal separator, nor
- * the <code>'0'</code> pattern character. Patterns such as <code>"@00"</code> or
- * <code>"@.###"</code> are disallowed.
- *
- * <li>Any number of <code>'#'</code> characters may be prepended to the left of the
- * leftmost <code>'@'</code> character. These have no effect on the minimum and maximum
- * significant digits counts, but may be used to position grouping separators. For
- * example, <code>"#,#@#"</code> indicates a minimum of one significant digits, a maximum
- * of two significant digits, and a grouping size of three.
- *
- * <li>In order to enable significant digits formatting, use a pattern containing the
- * <code>'@'</code> pattern character. Alternatively, call {@link
- * #setSignificantDigitsUsed setSignificantDigitsUsed(true)}.
- *
- * <li>In order to disable significant digits formatting, use a pattern that does not
- * contain the <code>'@'</code> pattern character. Alternatively, call {@link
- * #setSignificantDigitsUsed setSignificantDigitsUsed(false)}.
- *
- * <li>The number of significant digits has no effect on parsing.
- *
- * <li>Significant digits may be used together with exponential notation. Such patterns
- * are equivalent to a normal exponential pattern with a minimum and maximum integer digit
- * count of one, a minimum fraction digit count of <code>getMinimumSignificantDigits() -
- * 1</code>, and a maximum fraction digit count of <code>getMaximumSignificantDigits() -
- * 1</code>. For example, the pattern <code>"@@###E0"</code> is equivalent to
- * <code>"0.0###E0"</code>.
- *
- * <li>If signficant digits are in use, then the integer and fraction digit counts, as set
- * via the API, are ignored. If significant digits are not in use, then the signficant
- * digit counts, as set via the API, are ignored.
- *
- * </ul>
- *
- * <h4>Padding</h4>
- *
- * <p><code>DecimalFormat</code> supports padding the result of {@link #format} to a
- * specific width. Padding may be specified either through the API or through the pattern
- * syntax. In a pattern the pad escape character, followed by a single pad character,
- * causes padding to be parsed and formatted. The pad escape character is '*' in
- * unlocalized patterns, and can be localized using {@link
- * DecimalFormatSymbols#setPadEscape}. For example, <code>"$*x#,##0.00"</code> formats
- * 123 to <code>"$xx123.00"</code>, and 1234 to <code>"$1,234.00"</code>.
- *
- * <ul>
- *
- * <li>When padding is in effect, the width of the positive subpattern, including prefix
- * and suffix, determines the format width. For example, in the pattern <code>"* #0
- * o''clock"</code>, the format width is 10.
- *
- * <li>The width is counted in 16-bit code units (Java <code>char</code>s).
- *
- * <li>Some parameters which usually do not matter have meaning when padding is used,
- * because the pattern width is significant with padding. In the pattern "*
- * ##,##,#,##0.##", the format width is 14. The initial characters "##,##," do not affect
- * the grouping size or maximum integer digits, but they do affect the format width.
- *
- * <li>Padding may be inserted at one of four locations: before the prefix, after the
- * prefix, before the suffix, or after the suffix. If padding is specified in any other
- * location, {@link #applyPattern} throws an {@link IllegalArgumentException}. If there
- * is no prefix, before the prefix and after the prefix are equivalent, likewise for the
- * suffix.
- *
- * <li>When specified in a pattern, the 16-bit <code>char</code> immediately following the
- * pad escape is the pad character. This may be any character, including a special pattern
- * character. That is, the pad escape <em>escapes</em> the following character. If there
- * is no character after the pad escape, then the pattern is illegal.
- *
- * </ul>
- *
- * <p>
- * <strong>Rounding</strong>
- *
- * <p><code>DecimalFormat</code> supports rounding to a specific increment. For example,
- * 1230 rounded to the nearest 50 is 1250. 1.234 rounded to the nearest 0.65 is 1.3. The
- * rounding increment may be specified through the API or in a pattern. To specify a
- * rounding increment in a pattern, include the increment in the pattern itself. "#,#50"
- * specifies a rounding increment of 50. "#,##0.05" specifies a rounding increment of
- * 0.05.
- *
- * <ul>
- *
- * <li>Rounding only affects the string produced by formatting. It does not affect
- * parsing or change any numerical values.
- *
- * <li>A <em>rounding mode</em> determines how values are rounded; see the {@link
- * com.ibm.icu.math.BigDecimal} documentation for a description of the modes. Rounding
- * increments specified in patterns use the default mode, {@link
- * com.ibm.icu.math.BigDecimal#ROUND_HALF_EVEN}.
- *
- * <li>Some locales use rounding in their currency formats to reflect the smallest
- * currency denomination.
- *
- * <li>In a pattern, digits '1' through '9' specify rounding, but otherwise behave
- * identically to digit '0'.
- *
- * </ul>
- *

-/**
- * <code>DigitList</code> handles the transcoding between numeric values and
- * strings of characters. It only represents non-negative numbers. The
- * division of labor between <code>DigitList</code> and
- * <code>DecimalFormat</code> is that <code>DigitList</code> handles the radix
- * 10 representation issues and numeric conversion, including rounding;
- * <code>DecimalFormat</code> handles the locale-specific issues such as
- * positive and negative representation, digit grouping, decimal point,
- * currency, and so on.
- *
- * <p>A <code>DigitList</code> is a representation of a finite numeric value.
- * <code>DigitList</code> objects do not represent <code>NaN</code> or infinite
- * values. A <code>DigitList</code> value can be converted to a
- * <code>BigDecimal</code> without loss of precision. Conversion to other
- * numeric formats may involve loss of precision, depending on the specific
- * value.
- *
- * <p>The <code>DigitList</code> representation consists of a string of
- * characters, which are the digits radix 10, from '0' to '9'. It also has a
- * base 10 exponent associated with it. The value represented by a
- * <code>DigitList</code> object can be computed by mulitplying the fraction
- * <em>f</em>, where 0 <= <em>f</em> < 1, derived by placing all the digits of
- * the list to the right of the decimal point, by 10^exponent.
