Question

I’m trying to do some basic math and it keeps popping up as 0. I’m sure it has to do with it being an int but I don’t know how to work around it. I need to use integers but the math to arrive at those integers uses decimals. How do I do it?

Answer 1

This is not special to blackberry, it’s standard java behaviour.

This is because you’re doing integer math:

int subexpr1 = 14 / 20; // 0
int subexpr2 =  subexpr1 * 100; // 0

Use a double instead or change the order

int expr1 = (int) 14.0/20 * 100; // Very small possibility of rounding errors
int expr2 = 14 * 100 / 20; // Will ignore fraction parts
