Thanks. I think Axiom should expose functions like this in the
domains DoubleFloat and in Float. I remain a little confused about
how best to treat the LEAST_-POSITIVE_-LONG_-FLOAT in the case
of Axiom's Float domain.

Yes, it was the same problem that we have been having lately
with the server when the Python/Zope process just sits and
wastes CPU without accomplishing anything.

It should be ok now.

I have just finished upgrading MathAction to use a newer version
of Zope and Python 2.4. I hope that helps. Please let me know
if you continue to have problems accessing the server.

Thanks.
