<!-- ================================ DESCRIPTION  -->

    <refsect1 id="description"><title>Description</title>
		<para><function>min</function> returns <varname>y</varname> if <varname>y</varname> &lt; <varname>x</varname>, otherwise it returns <varname>x</varname>. If <varname>x</varname> and <varname>y</varname> are infinite or NaN, the return values are undefined.
		</para>

<!-- ================================ NOTES  -->

    <refsect1 id="notes"><title>Notes</title>
        <para>
		Built-in common functions operate component-wise and the description is per-component. We use the generic type name <type>gentype</type> to indicate that the
function can take <type>float</type>, <type>float2</type>, <type>float4</type>, <type>float8</type>, or <type>float16</type> as the type for the arguments.
		</para>
        <para>
		The built-in common functions are implemented using the round to nearest even rounding mode.
		</para>
		<para>
		If extended with <citerefentry><refentrytitle>cl_khr_fp64</refentrytitle></citerefentry>, generic type name <type>gentype</type> may indicate <type>double</type> and <type>double{2|4|8|16}</type> as arguments and return values. If extended with <citerefentry><refentrytitle>cl_khr_fp16</refentrytitle></citerefentry>, generic type name <type>gentype</type> may indicate <type>half</type> and <type>half{2|4|8|16}</type> as arguments and return values.
