    This is the classic integer divison question. One of your operands has to be a float for the division to work as you expect. – BradleyDotNET Jul 25 '14 at 16:20
  • Use `Convert.ToDouble(..)` for `a` and `b`. – afaolek Jul 25 '14 at 16:20

The expression (a / b) (where both a and b are ints) will result in an int, which is then converted to a float when assigned to c.

To get a float, you should make either a or b a float, or cast one to a float:

float c = (a / (float)b); // Int divided by float is a float

Or, just make a and b floats in the first place:

float a, b;

Because a and b are both integers, the result of division is also an integer. After the division, it is cast to a float, but it is too late by then.

For this to work, at least one of the operands must be a float. Try this:

float c = ((float) a) / b;
