If anyone has any pointers to well written guidelines for floating point
usage I would dearly love to hear about them.

I have seen the OLD Prentice Hall series (if my brain hasn't failed me)
text "Floating Point Computation".  I have seen the article in the ACM
Computing Reviews (again if the brain hasn't failed) a few years ago.
I have seen the text "Improving Floating Point ?" published recently.

But none of these seem to try to lay down a reasonably comprehensive set
of guidelines that individuals should consider when they begin floating
point computation.  If there were any contributions to such a set I am
almost provoked enough to try to take the best of everything that we know
about this subject and get it into book form.

Many many thanks
please use email if possible
