Question

Please forgive my programming knowledge. I know this is a simple thing, but I do not understand why result is always 0. Why decimal will be fine?

int a = 100;
int b = 200;
decimal c = (a / b) * 100;

Many thanks.

Answer 1

Integer division always truncates the remainder. This is done at the time that the number is divided, not when it’s assigned to the variable (as I’m guessing you assumed).

decimal c = ((decimal)a / b) * 100;
