05:34 <Orum> anyone know a fast(er) way to approximate this function? It only needs to work for 0 <= x <= 1 (though a and q could be anything): https://www.desmos.com/calculator/w1syvegcnq

05:36 <Orum> err, actually, 'a' will always be positive, and 0 <= q <= 1

06:39 <r4m0n> bit too flexible function, don't think you'll get it much simpler. it isn't that much expensive anyway. if you really need to call it thousands of times and it's slowing you down, I'd "cache" the results for a set of parameters (set $a and $q, store result for 10~100 steps of $x). then interpolate or use the cached results directly

06:40 <r4m0n> big tables of numbers make any calculation fast

07:02 <Orum> yeah, I suppose as long as I keep it small and linearly interpolate between or just round to the nearest it'll be fine
