cfractions
is a drop-in replacement for fractions
module
written using Python C API
.
Main features are:
- speed & memory efficiency compared to pure-
Python
counterpart, - full spectre of arithmetic & comparison operations,
Python3.6+
support,PyPy
support (by falling back tofractions.Fraction
proxy).
In what follows python
is an alias for python3.8
or pypy3.8
or any later version (python3.9

>>> from cfractions import Fraction
>>> Fraction()
Fraction(0, 1)
>>> Fraction(1, 2)
Fraction(1, 2)
>>> Fraction(50, 100)
Fraction(1, 2)
>>> Fraction(0.5)
Fraction(1, 2)
>>> Fraction(1, 3) + Fraction(1, 6)
Fraction(1, 2)
>>> Fraction(3, 2) - 1
Fraction(1, 2)
>>> 1 - Fraction(1, 2)
Fraction(1, 2)
>>> Fraction(1, 3) * Fraction(3, 2)
Fraction(1, 2)
>>> Fraction(1, 3) / Fraction(2, 3)
Fraction(1, 2)
>>> Fraction(1, 6) * 3
Fraction(1, 2)
>>> Fraction(3, 2) / 3
Fraction(1, 2)
>>> str(Fraction(1, 2))
