One could simply send the data through Base64 and store it as a single value

comment What math should all game programmers know?
in most cases you want atan2 since this takes care of the quadrant handling by itself.

comment 2d top-down map: normalisation or not?
Still using fixed-point values for absolute positions can be a good idea. This leads to constant precision and identical physics all over the world.

@jheriko you can hit a butterfly effect. You have sharp comparisons in your code, and the rounding error can happen to push a value over such a sharp boundary leading to quick resynchronization of the whole game state.

@BuleRaja Decimal is not fixedpoint. It is a floating point in base 10. And it's rather slow and large. Thus you don't want to use it in games.
