u/Jasper

Heya, I'm new to the site - what's the purpose of the OR in T=t|0? Is t sometimes undefined?
u/rep_movsd

t is time, but its in floating point, t|0 makes it an integer

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.
