Hi
This is a common problem for most math functions.
One of the problem is rounding to zero ( bad idea for
continuous number lines with positive and negative values ).
Floor math doesn't usually have such problems.

There are issues using 2Pi
because of rounding errors. Usually you end up having tolerance
values. Without tolerances, if someone rotates something by 90
degrees four times, they don't QUITE get what they started with when
using 2PI, but with degrees, they do.
Were are not talking about rotating an image here just projecting one.
