I found the a solution to the problem, it cannot be done just by " Leave scale 0 floats untouched ?"   which I tried, but also the Oracle parameter NLS_NUMERIC_CHARACTERS needed to be set explicitly. See http://www.osdir.com/ml/web.zope.database/2003-01/msg00036.html. That solved things for me.

Anyway, thanks Marc-Andre  :-)

There's a connection option " Leave scale 0 floats untouched ?" to switch
this off.

The truncation to integers is done because some database drivers always
return numbers as floats - even integers. Zope would then display these
as floats (without additional formatting), which may not look right to
the user.

See above: just switch on the option in the connection properties.
