FMAX(3) BSD Library Functions Manual FMAX(3)
NAME
fmax, fmaxf, fmaxl, fmin, fminf, fminl -- floating-point maximum and minimum functions
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 and NetBSD 5.1.
