If you want it fast, it's a hardware limitation. Isn't it theoretically
possible to emulate it in software at the cost of speed? (no, i can't offer
examples... just thought it is possible)
if someone really cared, it seems they could probably substitute math
subroutines in povray with a "big math" library.
i had a course on this in college. i forget every word about it, except that
I rendered a scene of the intersection of earth with a fictional comet as
part of a word problem for a homework assignment. bah
