For negative numbers unsigned-right-shift operator considers the binary representation of the negative number to be representative of a positive number.

    <script type="text/javascript">
    
        var oldValue = -64; //
        var newValue = oldValue >>> 5; //
        document.writeln(newValue);//134217726
