How to divide two longs and get the value?

Question

I need to compute probability of an integer and a long. but I always get 0.

int a = 234;
long b = 123453344L

float c = a /b;

How to get it right in Java?

Answer 1

You need to either cast one of them as a float, or declare one of the variables to be a float from the start. Otherwise, Java's integer division takes over, and just as an int divided by an int must be an int, that would apply to longs as well.

float c = (float) a / b;
