renox,

Very insightful. Beyond rounding issues, it's always bugged me a bit too that the resolution of game coordinates become worse and worse the further a player gets away from the origin. Therefor if your running precise mathematical computations in a game (ie object projections), the results inherently depend on which arbitrary digits the mantissa is representing. Using integral/fixed point arithmetic would offer equal precision at all coordinates.
