NAME

scalb, scalbf, significand, significandf – IEEE test functions

CONTENTS

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 -ieee754. Their use is not otherwise recommended.

scalb(x, n) and scalbf(x, n) return x, Ns, *(2**, Ns, Fa, n) computed by exponent manipulation. If n is not an integer, &#177;∞, or an NaN, the result is unspecified.

significand(x) and significandf(x) return sig, where x := sig, No, *, 2**, Ns, Fa, n with 1 ≤ sig < 2. significand(x) and significandf(x) are not defined when x is 0, &#177;∞, or NaN.
