Is there a faster alternative to python's Decimal?

Question

Does anyone know of a faster decimal implementation in python?

As the example below demonstrates, the standard library\'s decimal module is ~100 times slower than

Answer 1

You can try cdecimal:

from cdecimal import Decimal

As of Python 3.3, the cdecimal implementation is now the built-in implementation of the decimal standard library module, so you don't need to install anything. Just use decimal.

For Python 2.7, installing cdecimal and using it instead of decimal should provide a speedup similar to what Python 3 gets by default.
