The error looks like you are attempting to multiply a decimal by a
float which isn't allowed. Django coerces form fields like
DecimalField into a decimal object. See:
http://docs.python.org/library/decimal.html
for more information about the decimal object.
An error occurs like the one you have if you do something like:
>>> from decimal import Decimal
>>> import math
>>> d = Decimal("2")
>>> d*math.pi
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for *: 'Decimal' and 'float'
You can convert the decimal returned by the form into a float, or
convert the floats into decimals and do your math. Converting to
decimal is probably more precise.
Hope this helps,
