Try it this way:

double w = 12780d / 170d;

When you do math with doubles, you have to use doubles in the expression.

John, he's asking this from a Java perspective. Are you sure this works the same way in Java as in C#? (as in d being the suffix for double types)

You're right, Nish. Suffix 'd' doesn't work in Java. "123." is double, "123.f" is float.

or:
double w = 10*1280 / 170;
w = w/10 // w = 7.5
