Hi
Does anyone knows why, if I try System.out.println(8.2 - 1);, I get 7.199999999999999 as output ?

Thanx at advance !

I would guess decimal precision....but that's a far out guess. Have you tried assigning it to a single precision variable?

Hi, Thanx for your reply! I can't use Integer vars (or other var types that don't use decimal numbers) cause it's a calculator I'm making. I tried changing the type from double to float but still the same prob.. Any idea on how to solve this one ?
Thanx at advance !

Try this:

System.out.println(8.2f-1f);

8.2-1 is trying to subtract two different data types.
