chapter 8.3.5 of megapov documentation (about function pattern):
"valid function are: sin, cos, tan, radians, degrees, floor, ceil, pi"
but I've checked other functions and it works
in version 0.5 and in version 0.6
at thread "Fished onion" at p.b.i
you can find use of ln() and atan2()
anybody know why it is undocumented ?
or why there is not such words "and other functions"
at end of list in documentation ?
can I use any povray function/expresion with numeric result ?

The most likely reason: these functions just didn't exist in earlier
versions of the isosurface patch, and the documentation hasn't been
updated with these functions.

No. For example, you can't use eval_pattern(), strlen, etc.

I'm pretty sure you can't use mod() too, but I haven't dled 0.6 yet.

"float factor expected but mod found instead"? i think it was something like
that, which seems to me to suggest it's not valid in isosurface.

% might work, though. I don't remember for sure.
