It is interesting that when I do a #debug for a variable which I have
declared as [ #declare angie=2^3*4^4;]
povray tells me it is 1084576, when I paste this text (2^3*4^4) into
Lotus1-2-3, the result is 2048.
The Lotus 1-2-3 answer is based on the hierarchy of operators I remember
from grade school. Is povray's hierarchy of operators like that of C or
is it "new"?

How did you do that? POV doesn't have a ^ operator.

MegaPov does in the isosurface feature.

Yes, but he said he used #declare.

I wrote a patch which allows it to be used outside isosurface functions
as well. However, it doesn't do the precedence right, and I am not
certain how to fix it.

Ah, I see. It's been added to express.c in MegaPOV as well as to the isosurf
stuff. It wasn't added correctly, though; it has the same precedence as
multiply and divide. We'll need to make sure that gets fixed in 3.5.

It's worth noting that this is not a question for .general. If you're
using MegaPOV, and you're using a feature that isn't in the current official
version of POV-Ray or that works differently in the current official version
of POV-Ray, you should at least say so, and you should seriously consider
asking in the unofficial.patches newsgroup instead.
Is this in the "Welcome to the POV-Ray newsgroups" thingie in p.a.f-a-q?

Generally but not specifically.

Actually it is specific -
"*Unofficial Patches Group
There is an unofficial patches group where discussions on using other
peoples modified versions of POV-Ray are held."

When in doubt use parenthesis. They rule.
