Actionscript/Flex: Number Formatting (prefix a leading zero)

I was looking for a simple way to prefix a single digit number with a zero. I thought NumberFormatter would be able to do it, but turns out it can't. There is a project hosted on google for a bunch of tools that aren't included in Flex or Actionscript 3.

One of these tools allows you to prefix a number with a zero. It's in com.adobe.utils.NumberFormatter. The method is addLeadingZero(). It's kind of confusing having two NumberFormatter classes, but I didn't write it so there you go.

There's a lot of good stuff in the project, so if you're looking for something Flex doesn't do it might be in there.

I also wrote my own string padding function that can be used in Flex, AS2 or 3. Please see this post for more details.
