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

SYNOPSIS
       #include 

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

       Link with -lm.

   Feature Test Macro Requirements for glibc (see featuretestmacros(7)):

       fmax(), fmaxf(), fmaxl():
           XOPENSOURCE >= 600 || ISOC99SOURCE ||
           POSIXCSOURCE >= 200112L;
           or cc -std=c99

DESCRIPTION
       These functions return the larger value of x and y.

RETURN VALUE
       These functions return the maximum of x and y.

       If one argument is a NaN, the other argument is returned.

       If both arguments are NaN, a NaN is returned.

ERRORS
       No errors occur.

VERSIONS
       These functions first appeared in glibc in version 2.1.
