double d = 1000 / 3600; result in to a 0?

Question

I doing a simple calculation from 2 variable and I got in to an issue... In fact when I try to do " double d = 1000 (which is the first var) / 3600 (which is the 2nd var); it result in a 0. So why ? Any hint about that ?

Answer 1

1000 and 3600 are ints, so when you do 1000 / 3600 you get 0. Then, you are assigning double d to this result of zero. You can instead write 1000.0/3600.0 or if these two numbers are variables, you can cast them to doubles first.
