toUint32
Convert a double-precision floating-point number to an unsigned 32-bit integer.
Installation
npm install @stdlib/number-float64-base-to-uint32
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 );
