c# - how to convert Math.Ceiling result to int?

Question

Math.Ceiling returns double because double may store much bigger numbers. However if i'm sure that int type is capable to store the result how should I convert? Is it safe to cast (int) Math.Ceiling(... ?

Answer 1

If you are sure that you do not cross the capacity of int, it should be perfectly safe to do

int myInt = (int)Math.Ceiling(...);

If you are not sure about the bound, you could go with long instead of int.
