Returns <varname>y</varname> if <varname>x</varname> is less than <varname>y</varname>,
otherwise it returns <varname>x</varname>. If one argument is a NaN,
<function>fmax()</function> returns the other argument. If both arguments are NaNs,
<function>fmax()</function> returns a NaN.

<para>
<citerefentry><refentrytitle>fmin</refentrytitle></citerefentry> and
<function>fmax</function> behave as defined by C99 and may not match the IEEE 754-2008
definition for <function>minNum</function> and <function>maxNum</function> with regard
to signaling NaNs. Specifically, signaling NaNs may behave as quiet NaNs.
