fmin, fminf, fminl - determine minimum of two floating-point numbers
double fmin(double x, double y);
float fminf(float x, float y);
long double fminl(long double x, long double y);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
fmin(), fminf(), fminl():
_XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or cc -std=c99
These functions the lesser value of x and y.
These functions return the minimum 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.
