I was visiting RSI this morning and ran into two
of the people who ought to be following this discussion
closely. 

They are. In fact, they are *extremely* concerned about
math accuracy in IDL. If you know of specific problems,
and you haven't yet reported them to RSI's technical
support staff, this would be an *excellent* time to 
do so. :-)

One of their concerns, obviously, is the accuracy of
vendor-supplied libraries. We were discussing a
known VMS problem this morning. 

Cheers,

David
