FMAX(3) Linux Programmer's Manual FMAX(3)
fmax, fmaxf, fmaxl - determine maximum of two floating-point
numbers
#include <math.h>
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
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 first appeared in glibc in version 2.1.
For an explanation of the terms used in this section, see
attributes(7).
