Floating point is deterministic. It just depends on where you are. If your part is around a position like 32,64,128 or any power of 2, then the precision change and the rounding can differ.
What deen is talking about happened in Minecraft, it was called the Far lands. Game was totally broken if you'd go far enough (over 12 millions blocks away from the center).
