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