+// wuffs_base__private_implementation__hpd_left_shift[i] encodes the number of
+// new digits created after multiplying a positive integer by (1 << i): the
+// additional length in the decimal representation. For example, shifting "234"
+// by 3 (equivalent to multiplying by 8) will produce "1872". Going from a
+// 3-length string to a 4-length string means that 1 new digit was added (and
+// existing digits may have changed).
+//
+// Shifting by i can add either N or N-1 new digits, depending on whether the
+// original positive integer compares >= or < to the i'th power of 5 (as 10
+// equals 2 * 5). Comparison is lexicographic, not numerical.
+//
+// For example, shifting by 4 (i.e. multiplying by 16) can add 1 or 2 new
+// digits, depending on a lexicographic comparison to (5 ** 4), i.e. "625":
+// - ("1" << 4) is "16", which adds 1 new digit.
+// - ("5678" << 4) is "90848", which adds 1 new digit.
+// - ("624" << 4) is "9984", which adds 1 new digit.
+// - ("62498" << 4) is "999968", which adds 1 new digit.
+// - ("625" << 4) is "10000", which adds 2 new digits.
+// - ("625001" << 4) is "10000016", which adds 2 new digits.
+// - ("7008" << 4) is "112128", which adds 2 new digits.
+// - ("99" << 4) is "1584", which adds 2 new digits.
+//
+// Thus, when i is 4, N is 2 and (5 ** i) is "625". This etc__hpd_left_shift
+// array encodes this as:

+// - etc__hpd_left_shift[5] is 0x1009 = (? << 11) | 0x0009.

+// wuffs_base__private_implementation__powers_of_10 contains truncated
+// approximations to the powers of 10, ranging from 1e-326 to 1e+310 inclusive,
+// as 637 uint32_t quintuples (128-bit mantissa, 32-bit base-2 exponent biased
+// by 0x04BE (which is 1214)). The array size is 637 * 5 = 3185.
+//
+// The 1214 bias in this look-up table equals 1023 + 191. 1023 is the bias for
+// IEEE 754 double-precision floating point. 191 is ((3 * 64) - 1) and
+// wuffs_base__private_implementation__parse_number_f64_eisel works with
+// multiples-of-64-bit mantissas.
+//
+// For example, the third approximation, for 1e-324, consists of the uint32_t
+// quintuple (0x828675B9, 0x52064CAC, 0x5DCE35EA, 0xCF42894A, 0x000A). The
+// first four form a little-endian uint128_t value. The last one is an int32_t
+// value: -1140. Together, they represent the approximation to 1e-324:
+// 0xCF42894A_5DCE35EA_52064CAC_828675B9 * (2 ** (0x000A - 0x04BE))
+//
+// Similarly, 1e+4 is approximated by the uint64_t quintuple
+// (0x00000000, 0x00000000, 0x00000000, 0x9C400000, 0x044C) which means:
+// 0x9C400000_00000000_00000000_00000000 * (2 ** (0x044C - 0x04BE))
+//
+// Similarly, 1e+68 is approximated by the uint64_t quintuple
+// (0x63EE4BDD, 0x4CA7AAA8, 0xD4C4FB27, 0xED63A231, 0x0520) which means:
+// 0xED63A231_D4C4FB27.4CA7AAA8_63EE4BDD * (2 ** (0x0520 - 0x04BE))

-//
-// These tables are used in
-// wuffs_base__private_implementation__high_prec_dec__lshift_num_new_digits.
-
-// wuffs_base__private_implementation__hpd_left_shift[i] encodes the number of
-// new digits created after multiplying a positive integer by (1 << i): the
-// additional length in the decimal representation. For example, shifting "234"
-// by 3 (equivalent to multiplying by 8) will produce "1872". Going from a
-// 3-length string to a 4-length string means that 1 new digit was added (and
-// existing digits may have changed).
-//
-// Shifting by i can add either N or N-1 new digits, depending on whether the
-// original positive integer compares >= or < to the i'th power of 5 (as 10
-// equals 2 * 5). Comparison is lexicographic, not numerical.
-//
-// For example, shifting by 4 (i.e. multiplying by 16) can add 1 or 2 new
-// digits, depending on a lexicographic comparison to (5 ** 4), i.e. "625":
-// - ("1" << 4) is "16", which adds 1 new digit.
-// - ("5678" << 4) is "90848", which adds 1 new digit.
-// - ("624" << 4) is "9984", which adds 1 new digit.
-// - ("62498" << 4) is "999968", which adds 1 new digit.
-// - ("625" << 4) is "10000", which adds 2 new digits.
-// - ("625001" << 4) is "10000016", which adds 2 new digits.
-// - ("7008" << 4) is "112128", which adds 2 new digits.
-// - ("99" << 4) is "1584", which adds 2 new digits.
-//
-// Thus, when i is 4, N is 2 and (5 ** i) is "625". This etc__hpd_left_shift
-// array encodes this as:
-// - etc__hpd_left_shift[4] is 0x1006 = (2 << 11) | 0x0006.
-// - etc__hpd_left_shift[5] is 0x1009 = (? << 11) | 0x0009.
-// where the ? isn't relevant for i == 4.
-//
-// The high 5 bits of etc__hpd_left_shift[i] is N, the higher of the two
-// possible number of new digits. The low 11 bits are an offset into the
-// etc__powers_of_5 array (of length 0x051C, so offsets fit in 11 bits). When i
-// is 4, its offset and the next one is 6 and 9, and etc__powers_of_5[6 .. 9]
-// is the string "\x06\x02\x05", so the relevant power of 5 is "625".
