Math library (libm, -lm)
#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.
