    toInt32

    NPM version Build Status Coverage Status

    Convert an unsigned 32-bit integer to a signed 32-bit integer.

    Installation

    npm install @stdlib/number-uint32-base-to-int32

    Usage

    var uint32ToInt32 = require( '@stdlib/number-uint32-base-to-int32' );

    uint32ToInt32( x )

    Converts an unsigned 32-bit integer to a signed 32-bit integer.

    var float64ToUint32 = require( '@stdlib/number-float64-base-to-uint32' );
    
    var y = uint32ToInt32( float64ToUint32( 4294967295 ) );
    // returns -1
    
    y = uint32ToInt32( float64ToUint32( 3 ) );
    // returns 3

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var MAX_UINT32 = require( '@stdlib/constants-uint32-max' );
    var float64ToUint32 = require( '@stdlib/number-float64-base-to-uint32' );
    var uint32ToInt32 = require( '@stdlib/number-uint32-base-to-int32' );
    
    var uint32;
    var int32;
    var i;
    
    for ( i = 0; i < 100; i++ ) {
        // Generate a random unsigned 32-bit integer:
        uint32 = float64ToUint32( randu()*MAX_UINT32 );
    
        // Convert the unsigned integer to a signed 32-bit integer:
        int32 = uint32ToInt32( uint32 );
    
        console.log( 'uint32: %d => int32: %d', uint32, int32 );
    }
