NAME

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

SYNOPSIS

       #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 to

           scalb(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.
