Hi, I'm pleased to announce the release of cdecimal-2.2. cdecimal is a fast drop-in replacement for the decimal module in Python's standard library. Blurb ===== cdecimal is a complete implementation of IBM's General Decimal Arithmetic Specification. With the appropriate context parameters, cdecimal will also conform to the IEEE 754-2008 Standard for Floating-Point Arithmetic. Typical performance gains over decimal.py are between 30x for I/O heavy benchmarks and 80x for numerical programs. In a PostgreSQL database benchmark, the speedup is 12x. +---------+-------------+--------------+-------------+ | | decimal | cdecimal | speedup | +=========+=============+==============+=============+ | pi | 42.75s | 0.58s | 74x | +---------+-------------+--------------+-------------+ | telco | 172.19s | 5.68s | 30x | +---------+-------------+--------------+-------------+ | psycopg | 3.57s | 0.29s | 12x | +---------+-------------+--------------+-------------+ In the pi benchmark, cdecimal often performs better than Java's BigDecimal running on Java HotSpot(TM) 64-Bit Server VM. Both cdecimal and the underlying library - libmpdec - have very large test suites. libmpdec has 100% code coverage, cdecimal 85%. The test suites have been running continuously for over a year without any major issues. Install ======= Since cdecimal is now listed on PyPI, it can be installed using pip: pip install cdecimal Windows installers are available at: http://www.bytereef.org/mpdecimal/download.html Links ===== http://www.bytereef.org/mpdecimal/index.html http://www.bytereef.org/mpdecimal/changelog.html http://www.bytereef.org/mpdecimal/download.html Checksums of the released packages ================================== sha256sum --------- 3d92429fab74ddb17d12feec9cd949cd8a0be4bc0ba9afc5ed9b3af884e5d406 mpdecimal-2.2.tar.gz e8f02731d4089d7c2b79513d01493c36ef41574423ea3e49b245b86640212bdc mpdecimal-2.2.zip 515625c5c5830b109c57af93d49ae2c57ec3f230d46a3e0583840ff73d7963be cdecimal-2.2.tar.gz sha1sum ------- 24695b2c9254e1b870eb663e3d966eb4f0abd5ab cdecimal-2.2.win32-py2.6.msi e74cb7e722f30265b408b322d2c50d9a18f78587 cdecimal-2.2.win32-py2.7.msi 7c39243b2fc8b1923ad6a6066536982844a7617f cdecimal-2.2.win32-py3.1.msi 5711fd69a8e1e2e7be0ad0e6b93ecc10aa584c68 cdecimal-2.2.win-amd64-py2.6.msi b1cd7b6a373c212bf2f6aa288cd767171bfefd41 cdecimal-2.2.win-amd64-py2.7.msi f08a803a1a42a2d8507da1dc49f3bf7eed37c332 cdecimal-2.2.win-amd64-py3.1.msi cb29fa8f67befaf2d1a05f4675f840d7cd35cf6c cdecimal-2.2-no-thread.win32-py2.6.msi 012a44488f2ce2912f903ae9faf995efc7c9324b cdecimal-2.2-no-thread.win32-py2.7.msi 1c08c73643fc45d7b0feb62c33bebd76537f9d02 cdecimal-2.2-no-thread.win32-py3.1.msi b6dbd92e86ced38506ea1a6ab46f2e41f1444eae cdecimal-2.2-no-thread.win-amd64-py2.6.msi b239b41e6958d9e71e91b122183dc0eaefa00fef cdecimal-2.2-no-thread.win-amd64-py2.7.msi 413724ff20ede7b648f57dd9a78a12e72e064583 cdecimal-2.2-no-thread.win-amd64-py3.1.msi Stefan Krah
