ok, lots of testing, and I have found that this is related to Mysql 5.0.4.

I compiled and installed Mysql 5.0.0 and the problem does not exist. I
guess means that it started in 5.0.1 or higher.  I read through the
change logs and saw a couple of items related to float values on 5.0.3
and 5.0.4, but I dont have any idea if those are causing the issue.

So, I dont know where to go next.  I can post this info on the mysql
lists, but I only see the problem in Zope.  Python, or at least the
MysqlDA, retrieves the value just fine.  I only get the problem if
using a fmt option on Zope.
Here's a recap: 
-- I can use Zope 2.7.4 with Mysql 5.0.4 on Windows (using Egenix ODBC
DA) and there is no issue.
-- I can use Zope 2.7.3 with Mysql 5.0.0 on Linux (Zmysqlda 2.0.9b3,
Mysql-python1.2.0,Python 2.3.4) and there is no issue.
-- When using Zope 2.7.3 with same setup as before, but with Mysql
5.0.4, problem exists.
-- Zope 2.7.6 has same issue.

I tried doing a simple dtml:
<dtml-call "REQUEST.set('dec',10.23)">
<dtml-var dec><br>
<dtml-var dec fmt="dollars-and-cents"><br>

This works just fine.  But when pulling 'dec' from Mysql, dtml wont
render it if using fmt.

I dont have to use Mysql 5.x.  It's just that I already have the app
running on it, and I'd like to start testing the stored procedures and
other useful features.

Sorry for the long post.  I just want to give as much info as
possible.  Thank you for any help!

Greg
