Thread: Formatting my output

How do I change my numbers at the end so that instead of showing 0 it shows 0.00 or instead of showing 5.3 it shows 5.30?
I want only the winnings to be showing in this format.

I have tried that and it hasn't worked, I'm not just waiting to be spoonfed, I came on a website that was supposed to help.
