IEEE_TEST(3)						   BSD Library Functions Manual 					      IEEE_TEST(3)

NAME
scalb, scalbf, significand, significandf -- IEEE test functions LIBRARY
Math Library (libm, -lm) SYNOPSIS
#include <math.h> double scalb(double x, double n); float scalbf(float x, float n); double significand(double x); float significandf(float x); DESCRIPTION
These functions allow users to test conformance to IEEE Std 754-1985. Their use is not otherwise recommended. scalb(x, n) and scalbf(x, n) return x*(2**n) computed by exponent manipulation. If n is not an integer, +-infinity, or an NaN, the result is unspecified. significand(x) and significandf(x) return sig, where x := sig * 2**n with 1 <= sig < 2. significand(x) and significandf(x) are not defined when x is 0, +-infinity, or NaN.

NAME
significand, significandf, significandl - significand function SYNOPSIS
c99 [ flag... ] file... -lm [ library... ] #include <math.h> double significand(double x); float significandf(float x); long double significandl(long double x); DESCRIPTION
If x equals sig * 2^n with 1<= sig < 2, then these functions return sig. RETURN VALUES
Upon successful completion, these functions return sig. If x is either 0, +-Inf or NaN, x is returned. ERRORS
No errors are defined. ATTRIBUTES
