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.
This function came from BSD.
