No need. The Python tutorial says mixing integers and decimals in
arithmetic is OK.
Note version 2.7.1 in the following.
cjk@mid-tower:~$ python
Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53)
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from decimal import Decimal
>>> foo = Decimal('1.5')
>>> foo + 2
Decimal('3.5')
And here is why one should not use float for currency:
>>> bar = float(3.14)
>>> bar + 2
5.140000000000001
>>> fooble = float('3.14')
>>> fooble + 2
5.140000000000001
An alternative way to do math with currency is multiply everything by
1000 and do integer math on the results.
Just remember to do the appropriate division for output to views.
