is it all similar to c(++)?
thanks

sorry for my pronounciation. i ment <hint>.

#if (mod((cm*100)/1) = 0)

I think you have POV-Ray installed with documentation but if not (POV
3.5 allow to not instal doc) please look at
http://www.povray.org/working-docs/id000135.html#6_1_3_6 - there is
list of float functions (also mod) for current beta version of POV 3.5
but most of them (i.e. mod) works fine with erlier versions.

BTW: there are much more advanced questions within
povray.newusers group :-)

: BTW: there are much more advanced questions within
: povray.newusers group :-)
Which raises a question: Why do people post trivial questions in this
group? They should know that asking the syntax for a trivial function is
far from advanced.

The usual thinking seems to go "well, this is where the advanced users
hang out, so someone here is sure to know the answer to my question."
Either that or the definition of advanced is "anyone more advanced than
me."

Of course, then you've got the other extreme, where people think "My
question isn't advanced enough for this group," and it may or may not be
true, but I think it results in this group being very infrequently posted
to. What *would* qualify as an advanced question or discussion topic?

BTW: until i do not have installed ht:dig it is a hard job to "fight
through the fucking manual". rtfm turns to ftfm ;-)
an interesting interesting thing is: where is the border to an advanced
question. (but no discussion about it please, i will post to newusers
futurely.)

"How do I calculate the normal vector of an isosurface function at a
