Hi, Thanks for the info, I'll try it. Do you know why this should give me a speed-up?
Division is a much more complex operation to do in a computer than multiplication (think about when you learned how to solve large division problems when you were young), so it is slower on most processors. Finding a way to avoid division when some other operation will give you what you want is always a good idea.
