Low Word

Return an unsigned 32-bit integer corresponding to the less significant 32 bits of a double-precision floating-point number.

Usage

var getLowWord = require( '@stdlib/number/float64/base/get-low-word' );

getLowWord( x )

Returns an unsigned 32-bit integer corresponding to the less significant 32 bits of a double-precision floating-point number.

var w = getLowWord( 3.14e201 ); // => 10010011110010110101100010000010
// returns 2479577218

Examples

var floor = require( '@stdlib/math/base/special/floor' );
var randu = require( '@stdlib/random/base/randu' );
var pow = require( '@stdlib/math/base/special/pow' );
var getLowWord = require( '@stdlib/number/float64/base/get-low-word' );

var frac;
var exp;
var w;
var x;
var i;

for ( i = 0; i < 100; i++ ) {
    frac = randu() * 10.0;
    exp = -floor( randu()*324.0 );
    x = frac * pow( 10.0, exp );
    w = getLowWord( x );
    console.log( 'x: %d. low word: %d.', x, w );
