#include <math.h>

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

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

fmax(), fmaxf(), fmaxl():


    _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

These functions return the larger value of x and y.

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.

No errors occur.

These functions were added in glibc 2.1.

For an explanation of the terms used in this section, see attributes(7).
