SYNOPSIS

       #include <math.h>

       double fmin(double x, double y);
       float fminf(float x, float y);
       long double fminl(long double x, long double y);

   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       fmin(), fminf(), fminl():
           _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

DESCRIPTION

       These functions return the lesser value of x and y.

RETURN VALUE
