This package implements a light-weight installable Django app for manipulating models with dollar values. (It should work for other currencies too if you forgive my U.S.-centric naming conventions.)
The package builds on Django's DecimalField by adding some simple logic
for currency rounding rules (all amounts rounded to two decimal places, always
rounding up). There are two main classes to be aware of:
Dollar: A wrapper class for arithmetic operations with dollar valuesDollarField: A custom field for representing dollar values in models
