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.
