NAME

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

LIBRARY

Math library ( libm , -lm )

SYNOPSIS

#include <math.h>

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

Feature Test Macro Requirements for glibc (see feature_test_macros (7)):

significand (), significandf (), significandl ():
/* Since glibc 2.19: */ _DEFAULT_SOURCE
|| /* glibc <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE

DESCRIPTION

These functions return the mantissa of x scaled to the range [ 1 , FLT_RADIX ). They are equivalent to

scalb(x, (double) -ilogb(x))

This function exists mainly for use in certain standardized tests for IEEE 754 conformance.
