toUint32

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

Usage

var float32ToUint32 = require( '@stdlib/number/float32/base/to-uint32' );

float32ToUint32( x )

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

var float64ToFloat32 = require( '@stdlib/number/float64/base/to-float32' );

var y = float32ToUint32( float64ToFloat32( 4294967297.0 ) );
// returns 0

y = float32ToUint32( float64ToFloat32( 3.14 ) );
// returns 3

y = float32ToUint32( float64ToFloat32( -3.14 ) );
// returns 4294967293

y = float32ToUint32( float64ToFloat32( NaN ) );
// returns 0

y = float32ToUint32( float64ToFloat32( Infinity ) );
// returns 0

y = float32ToUint32( float64ToFloat32( -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 float64ToFloat32 = require( '@stdlib/number/float64/base/to-float32' );
var float32ToUint32 = require( '@stdlib/number/float32/base/to-uint32' );

var uint32;
var half;
var f32;
var i;

half = ( MAX_INT-1 ) / 2;
for ( i = 0; i < 500; i++ ) {
    // Generate a random single-precision floating-point integer:
    f32 = float64ToFloat32( round( randu()*MAX_INT ) - half );

    // Convert the single-precision floating-point value to an unsigned 32-bit integer:
    uint32 = float32ToUint32( f32 );

    console.log( 'float32: %d => uint32: %d', f32, uint32 );
