division

Hello,

Im astonished. Im trying this simple calculation in a Java application:

System.out.println("b=" + (1 - 7/10));

Obviously Im wainting for "b=0.3" in the output but here's what I get:

b=1

What?! Why this happens?

If I make:

System.out.println("b=" + (1-0.7));

I get the right result which is "b=0.3".

What's going wrong here?

Thanks!
