fmax, fmaxf, fmaxl − determine maximum of two floating-point numbers
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():
_XOPEN_SOURCE >= 600
|| _ISOC99_SOURCE ||
_POSIX_C_SOURCE >= 200112L;
or cc -std=c99
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).
