NAME

       fmax,  fmaxf,  fmaxl - determine maximum numeric value of two floating-
       point numbers

SYNOPSIS

       #include <math.h>

       double fmax(double x, double y);
       float fmaxf(float x, float y);
       long double fmaxl(long double x, long double y);

DESCRIPTION

       These functions shall determine the  maximum  numeric  value  of  their
       arguments.  NaN  arguments  shall  be  treated  as missing data: if one
       argument is a NaN and the other numeric,  then  these  functions  shall
       choose the numeric value.

RETURN VALUE

       Upon  successful  completion,  these functions shall return the maximum
       numeric value of their arguments.

       If just one argument is a NaN, the other argument shall be returned.

       If x and y are NaN, a NaN shall be returned.
