It seems that the formatting can only happen in the final output. Doesn't seem it can be used in a Double Variable. So if I wanted to create a Double, to just hang on to this formatting, can't be done. Maybe you could help me, and show me how it can be stored in a variable. I actually got what I wanted, but I also would like to know how to store the value in a Variable, preferably a Double. For what it's worth, thanks. (+1 : 29).

If you could help, with declaring a variable, while holding the formatted number, that would be very good. I'd be very grateful. I'm working with Android Studio, so learning Java is helping me allot. Not making any money, just doing small Calculating Apps for my personal use. On my Samsung Galaxy Note 4.

@hellsing357 It's recommended that you just use the 0s.
