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 first appeared in glibc in version 2.1.
