Description:
pypicdecimal 2.3
Overview
The cdecimal package is a fast drop-in replacement for the decimal module
in Python’s standard library. Both modules provide complete implementations of
Mike Cowlishaw/IBM’s General Decimal Arithmetic Specification.
Testing
Both cdecimal and the underlying library - libmpdec - are extremely
well tested. libmpdec is one of the few open source projects with 100%
code coverage. cdecimal is rigorously tested against decimal.py.
Short benchmarks
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.

Documentation
Since cdecimal is compatible with decimal.py, the official documentation
is valid. For the few remaining differences, refer to the second link.

Linux Notes
The build process requires a working C compiler and a full Python install with
development headers. Linux distributions often ship the Python header files as
a separate package, called python-dev or python-devel.
Install headers on Debian/Ubuntu:
sudo apt-get install python-dev
