FMAX(3) FreeBSD 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.
