Decimal compatability with float

Features

Implicit float-to-Decimal coercion for arithmetic operations.

Instead of this:

>>> from decimal import Decimal
>>> Decimal(12.0) * 0.5
TypeError: unsupported operand type(s) for *: 'Decimal' and 'float'

Use FDecimal:

>>> from fdecimal import FDecimal
>>> FDecimal(12.0) * 0.5
Decimal('6.0')

As you can see it only solves part of the problem - the result still can’t be added with a float value without explicit type coercion, but it solves some problems where (1) its not clear what type the other value will be, (2) you don’t want to add code explicitly handling that coercion, and (3) an arithmetic surprises due to working with different numeric types are acceptable.

TODO

• Missing operations, including mod, floor div

• Python 3 support

• Allow cdecimal swap-in

Done:

• Return FDecimal objects rather than Decimal objects
