significand(), significandf()

IEEE test functions 

Function


SYNOPSIS

#include <math.h>

double significand(double x)

float significandf(float x)


DESCRIPTION

significand(x) returns sig, where x := sig* 2**n with 1 <= sig < 2. significand(x) is not defined when x is 0, ┬▒Infinity, or NaN.

The significandf() function is a single-precision version of significand().


PARAMETERS

x 

Is the number whose significand is to be computed.


RETURN VALUES

If successful, significand() returns the value of the function.

significand(x) is not defined when x is 0, ┬▒Infinity, or NaN.


CONFORMANCE

IEEE Std 754-1985


MULTITHREAD SAFETY LEVEL

MT-Safe.


PORTING ISSUES
