I fully agree with Theo, I've been reading this interesting thread
and I'm a bit concerned. I don't use heavy duty math routines
extensively, but I use a few that I could not be sure if they
are really working correctly. Some people posting to this thread
have mentioned (seemingly knowingly) problems in some IDL math routines.
I've seen a few examples mentioned, but a list of known problems would
be very useful. Is there such a list compiled anywhere? If not,
could those doing the talking help in creating one?
