toUint32

Convert a double-precision floating-point number to an unsigned 32-bit integer.

Usage

var float64ToUint32 = require( '@stdlib/number/float64/base/to-uint32' );

float64ToUint32( x )

Converts a double-precision floating-point number to an unsigned 32-bit integer.

var y = float64ToUint32( 4294967297.0 );
// returns 1

y = float64ToUint32( 3.14 );
// returns 3

y = float64ToUint32( -3.14 );
// returns 4294967293

y = float64ToUint32( NaN );
// returns 0

y = float64ToUint32( Infinity );
// returns 0

y = float64ToUint32( -Infinity );
// returns 0

Examples

var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var MAX_INT = require( '@stdlib/constants/uint32/max' );
var float64ToUint32 = require( '@stdlib/number/float64/base/to-uint32' );

var uint32;
var half;
var f64;
var i;

half = ( MAX_INT-1 ) / 2;
for ( i = 0; i < 500; i++ ) {
    // Generate a random double-precision floating-point integer:
    f64 = round( randu()*MAX_INT ) - half;

    // Convert the double-precision floating-point value to an unsigned 32-bit integer:
    uint32 = float64ToUint32( f64 );

    console.log( 'float64: %d => uint32: %d', f64, uint32 );
