    NPM version Build Status Coverage Status dependencies

    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 );
    }

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
