@FioraAeterna why don't GPUs use fixed-point?
@stephentyrone @whitequark @FioraAeterna But fixed point is utterly awful when you also have to represent anything beyond that.

@RichFelker@whitequark@FioraAeterna and woe unto you when you need to make the coordinate space a little bit bigger. -
@stephentyrone@whitequark@FioraAeterna Well the same problem can happen with float but it's more subtle (and thus more ugly/dangerous). -
@stephentyrone@whitequark@FioraAeterna Increasing the size of your float coordinate space gives "more discrete than others" regions. -
@stephentyrone@whitequark@FioraAeterna For [in-bound-]translation-invariance, float spaces should be centered around 0x1.8pN for N big.
