Well, I wasn''t technically accurate in what I said. I do want to increment by 0.1 each time but I want to specify how many times (pixels the mouse has moved). I want to try using a loop instead and see if that would do anything to improve the accuracy.

Thanks

Since all the variables in your problem are essentially measured as integer values (number of pixels travelled, mouse input value, milliseconds of time), then the most accurate thing to do for that case is simply move everything to integer.

That should only really require a few integer multiplies more to account for things such as converting "pixels moved per milisecond" to "pixels moved per second".

The point of the replies to this thread are more that floating point has its place when you need a much greater range than say 2^32. But can''t represent *everything*. If you need every value in a range, use fixed point or similar.
