New submission from Carsten Grohmann <carstengrohmann at gmx.de>:


the documentation of the decimal module contains a small recipe called moneyfmt() for format decimal values. It's very usefull.

I'd like to suggest a small improvement because the output is incorrect with given dp="." (default) and places=0.

>>> moneyfmt(decimal.Decimal('-0.02'), neg='<', trailneg='>', places=1)
>>> moneyfmt(decimal.Decimal('-0.02'), neg='<', trailneg='>', places=0)

+    if places:

     if not digits:
     i = 0

What do you think about the change?
