SYNOPSIS
#include <math.h>
double significand(double x);
float significandf(float x);
long double significandl(long double x);
Link with -lm.
DESCRIPTION
The significand() function returns the mantissa of x scaled to the range [1,2). It is equivalent to scalb(x, (double) -ilogb(x))
This function exists mainly for use in certain standardized tests for IEEE 754 conformance.
