Yes... I see the point. Correct.
For a constant value this is true, in the instance of x = x + 1 (which I see where the error was), where x is a float this makes no difference.
However, for clarity of the OP, x = x + y where y is an int, should be typecast correctly as x = x + (float)y
Personally when I am writing code, I always write as x = x + 1.0 for clarity as well.
Sorry for not understanding the rebuttal :*)
