Integer based MoneyField

It is supposed the aggregation on integer is fast than numeric type in database duo to how they are stored as numeric is represented as string. As money only have 2 decimal place, it can be converted to an Integer despite of its decimal point. The python class decimal.Decimal also has a shortcoming that it is not json serializable(neither cjson nor simplejson). This money field appears as a float number to the front end, so it does not meet the headache as DecimalField. The usage is very simple. In Model: class SomeModel(models.Model): ... income = MoneyField('income') ... Then treat the attribute of the model instance as a normal float type. **Notes** If you try to use aggregation on this field, you have to convert it to float by yourself. Currently I could not find any method to fix this.
