that is bullshit.  i won't look for a page to quote
from this time :) , but i bet there are plenty.

or maybe you should look up "modulo calculus" for
yourself.

yes, i understand this now (Will's explanation was
very helpful for my understanding of povray's use
for div and mod, and why it is a little, um,
"different". ;)

however, i agree with Andrew that it is a bit strange
from a mathematician's perspective.

the only solution would be to use macros for other
implementations, if one needs them, as hardly anybody
would agree if someone asked the pov team to rename,
say, "div" to "symdiv" and add another function..

i disagree!  ;)
