General Decimal Arithmetic
While trying to find out if Python included some built-in capabilities for dealing with BCD numbers (it appears not) I encountered this rather interesting page about decimal arithmetic.

Not exactly direct support but close. You can use hex() or write a method to convert the BCD to a string of digits then to a Decimal object. See the decimal module.
