fmin(3M)						  Mathematical Library Functions						  fmin(3M)

NAME

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

SYNOPSIS

       cc [ flag... ] file... -lm [ library... ]
       #include <math.h>

       double fmin(double x, double y);

       float fminf(float float x, float y);

       long double fminl(long double x, long double y);

DESCRIPTION

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

RETURN VALUES

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

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

       If x and y are NaN, a NaN is returned.

ERRORS

       No errors are defined.
