```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 manipu‐
lation.  If n is not an integer, ±∞, or an NaN, the result is unspeci‐
fied.

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, ±∞, or NaN.
