to return Decimal instances in Python for this field. Backwards incompatible change. Added a real FloatField (stores floats in the database) and support for FloatField and DecimalField in newforms (analogous to IntegerField). Included decimal.py module (as django.utils._decimal) from Python 2.4. This is license compatible with Django and included for Python 2.3 compatibility only. Large portions of this work are based on patches from Andy Durdin and Jorge Gajon. git-svn-id: http://code.djangoproject.com/svn/django/trunk@5302 bcc190cf-cafb-0310-a4f2-bffc1f526a37
