NAME
fmax, fmaxf, fmaxl, fmin, fminf, fminl — floating-point maximum and minimum functionsLIBRARY
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.
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.June 29, 2004 | FreeBSD |
