NAME

fmax, fmaxf, fmaxl, fmin, fminf, fminl — floating-point maximum and minimum functions

SYNOPSIS

Math Library (libm, -lm)
#include <math.h>

double
fmax(double x, double y);

float
fmaxf(float x, float y);

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

double
fmin(double x, double y);

float
fminf(float x, float y);

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

DESCRIPTION

The fmax(), fmaxf(), and fmaxl() functions return the larger of x and y, and likewise the fmin(), fminf(), and fminl() functions return the smaller of x and y. They treat +0.0 as being larger than -0.0. If one argument is an NaN, then the other argument is returned. If both arguments are NaNs, then the result is an NaN. These routines do not raise any floating-point exceptions.

SEE ALSO

fabs(3), fdim(3)

STANDARDS

The fmax(), fmaxf(), fmaxl(), fmin(), fminf(), and fminl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).

HISTORY

These routines first appeared in OpenBSD 4.5.
