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
