Also people writing floating point off because it does not fit well into situations where you have evenly divide something (e.g galaxy into picometer sized voxels) show fundamental lack of understanding how floating point works. One of the biggest reasons floats are used is that error propagation is much better when floats are used in many numerical algorithms. In a nutshell. If you want coordinates in galaxy use fixed point (or in game level). If you want to calculate values of hyperbolic trigonometric functions or whatever use floats.
