- GFK_of_xmaspast 11y agoIsn't this exactly the kind of situation you'd use a CORDIC for?
- Udo 11y agoThis is very clever. I remember first coming across this problem a long time ago when improvising my first "vector"-based program on the 286, which I programmed in Pascal at the time. My "solution" was to pre-calculate the values and throw them into a lookup table - which in hindsight was pretty clumsy compared to this.
- GFK_of_xmaspast 11y agoIf you have the memory, a lookup table is a perfectly reasonable solution.
