NAME
fmaximum_mag_num, fmaximum_mag_numf, fmaximum_mag_numl, fminimum_mag_num, fminimum_mag_numf, fminimum_mag_numl – floating-point maximum and minimum magnitude number functions
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
fmaximum_mag_num(double x, double y);
float
fmaximum_mag_numf(float x, float y);
long double
fmaximum_mag_numl(long double x, long double y);
double
fminimum_mag_num(double x, double y);
float
fminimum_mag_numf(float x, float y);
long double
fminimum_mag_numl(long double x, long double y);
DESCRIPTION
The fmaximum_mag_num(), fmaximum_mag_numf(), and fmaximum_mag_numl() functions determine the larger of the absolute values of x and y, and return the argument with the larger absolute value, preferring a numeric value over an . If one argument is a numeric value and the other is an , the numeric value is returned. If the absolute values are equal, the behavior is equivalent to calling the corresponding fmaximum_num() function on the arguments.
Likewise, the fminimum_mag_num(), fminimum_mag_numf(), and fminimum_mag_numl() functions determine the smaller of the absolute values of x and y, and return the argument with the smaller absolute value, preferring a numeric value over an . If one argument is a numeric value and the other is an , the numeric value is returned. If the absolute values are equal, the behavior is equivalent to calling the corresponding fminimum_num() function on the arguments.
If both arguments are s, a quiet is returned. If either argument is a signaling , an invalid exception is raised. Otherwise, these routines do not raise any floating-point exceptions.
