What is the best django model field to use to represent a US dollar amount?

Question

I need to store a U.S. $ dollar amount in a field of a Django model. What is the best model field type to use? I need to be able to have the user enter this value (with error checking, only want a number accurate to cents), format it for output to users in different places, and use it to calculate other numbers.

Answer 1

Decimal if django has it.

Answer 2

A decimal field is the right choice for the currency value.
