quicktions 1.0 has been released, the cythonized version of
'fractions.Fraction'. It works with CPython 2.6 - 3.5.
Get it from PyPI:
Python’s Fraction data type is an excellent way to do exact fractional and
money calculations and largely beats Decimal in terms of simplicity,
accuracy and safety. Clearly not in terms of speed, though, given the
cdecimal accelerator in Py3.3+.
"quicktions" is an adaptation of the original fractions module (as included
in CPython 3.5) that is compiled and optimised with Cython into a fast,
native extension module.
Compared to the standard library ‘fractions’ module in Py2.7 and Py3.4,
"quicktions" is currently about 10x faster, and still about 6x faster than
the current version in Python 3.5. It’s also about 15x faster than the
(Python implemented) decimal module in Py2.7.
For documentation, see the Python standard library’s fraction module:
