FMAX(3)

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

LIBRARY
libm

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. If one argument is an , then the other argument is returned. If both arguments are s, then the result is an . 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 isoC-99.

CAVEATS
The library implementations of these functions treat +0.0 as being larger than -0.0. This behavior is not specified by the C standard, is not portable, and may not occur in light of compiler optimizations.

HISTORY
These routines first appeared in FreeBSD 5.3.
