The cdecimal is a fast drop-in replacement for the decimal module in Python's
standard library. Both modules provide complete implementations of the General
Decimal Arithmetic Specification.
Typical performance gains are between 30x for I/O heavy benchmarks and 80x for
numerical programs. In a database benchmark, cdecimal exhibits a speedup of
12x over decimal.py.
decimal cdecimal speedup
pi 42.75s 0.58s 74x
telco 172.19s 5.68s 30x
psycopg 3.57s 0.29s 12x
All Python versions from 2.5 up to 3.2 are supported. For the few remaining
differences, read the cdecimal documentation. cdecimal has been included in
Python-3.3.
