fmin fminf fminl — determine minimum numeric value of two floating-point numbers

#include <math.h>

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

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 (“POSIX.1”) defers to the ISO C standard.

These functions shall determine the minimum numeric value of their arguments. NaN arguments shall be treated as missing data: if one argument is a NaN and the other numeric, then these functions shall choose the numeric value.

Upon successful completion, these functions shall return the minimum numeric value of their arguments.

If just one argument is a NaN, the other argument shall be returned.

If and are NaN, a NaN shall be returned.

No errors are defined.
