Seems there is no clear answer (I even asked on the DB-SIG mailing 
list). If you use '%f' format then I think you should make sure you 
operate with finite values.

So I've checked this in anyway, similar to what Maxim suggested, but 
with some changes to make it work with older Py versions down to 2.3.

The datetime.date issue should be handled separately, it is now at
