NAME

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

CONTENTS

LIBRARY

Math Library (libm, -lm)

SYNOPSIS

#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), math(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 FreeBSD 5.3 .

“ Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.” ”
