Round a decimal number upto two digits after decimal

Hi,

I have a number say 13.34445466 , I want to round this to two digits after decimal. I want to do this in javascript.

    function roundNumber(inputNumber, numberOfDigits)

    {

        var multiple = Math.pow(10, numberOfDigits);

        var output = Math.round(inputNumber * multiple) / multiple;

        return output;

    }
