I've tried a couple of math formula's, and using java.text.decimalformatter buut, I'm not having much luck. I need something that not only works for decimals with a large amount of numbers after the decimal point. But also something that works for converting an int 30, to double 30.0 and than gives me 30.00...if possible. Is it?
