NAME
significand, significandf, significandl - get mantissa of floating-point numberSYNOPSIS
#include <math.h>
double significand(double x);
float significandf(float x);
long double significandl(long double x);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
significand(), significandf(), significandl(): _SVID_SOURCE || _BSD_SOURCE
DESCRIPTION
The significand() function returns the mantissa of x scaled to the range [1,2). It is equivalent toscalb(x, (double) -ilogb(x))
This function exists mainly for use in certain standardized tests for IEEE 754 conformance.
CONFORMING TO
These functions are nonstandard; the double version is available on a number of other systems.SEE ALSO
