NAME

significand, significandf, significandl - get mantissa of floating point number

#include <math.h>

double significand(double x);
float significandf(float x);
long double significandl(long double x);

Link with -lm.

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.
