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

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