appending a zero

[ellcon]

Hi, I need to know how to append a zero to the front of a number. For example, how to change 6 into 06.
Thanks

iNum = 6;
paddedNum = "0" + iNum;

===============

iNum = 6;
iPaddedLength = 2;
paddedNum = ""+iNum;
while (paddedNum.length < iPaddedLength) {
paddedNum = "0" + paddedNum;
}
