    To compute square number you only need the number squared - i.e. multiplied by itself.

    Are you sure it is your problem?

    Perhaps you meant "Square Root"?

    There is a ready method Math.sqrt(x)...

    If you want to calculate it without library methods you can use either "Babylonyan method" - you can find comprehensive description here:
    Wiki: Square Root Approximation - CodeAbbey

    Or you can even use binary search.
