Why is this inaccurate?

Can't figure out this thing for the life of me, I have the same equations in another application I'm making, and its perfect, why is this not working? (should be easy to figure out, its two events lol)

It comes from storing values in an object's X and Y co-ordinates, which are always rounded to whole numbers. I get around this by using a couple of alterable values as "virtual x" and "virtual y" values, and always setting the object's position based on those instead:

Lol that's quite annoying, thanks anyways, good to have a solution.
