i was thinking about using integers for some grid-based distance stuff just for sanity — and perhaps portability to retro consoles…
the 24/17 one is nice, because you can do 12/17 and approx invsqrt(2). only problem is dividing by 17 when the time comes.
something interesting is that, if you are gonna use x/17 for coordinates, 255/17 is exactly 15 and 65535/17 is exactly 3855. seems like this works for any 2**(8*Z)-1
