fmax, fmaxf, fmaxl − determine maximum of two floating-point numbers
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.
No errors occur.
