There's a difference in the way the float is rounded which you can see by changing your float to 123.55f: float ft = 123.55f; int nm = (Int32)ft; int nm2 = Convert.ToInt32(ft); Console.WriteLine(nm); // 123 Console.WriteLine(nm2); // 124 A cast always rounds towards zero. However Convert.ToInt32 rounds to the nearer integer. If the float is halfway between two integers the even integer is returned. So 123.5f would round to 124 rather than 123.
