Of course I don't know exactly how the game engine works, but I know I'm real close. I suspect the difference may only be in how the engine rounds numbers. The engine may only use whole numbers (ignoring all decimal points) or it may round numbers in the traditional fashion. It may even use a mixture of the two depending if it's part of the equation or the final result
