Fraction 1.4.1

Fraction carries out all the fraction operations including addition, subtraction, multiplication, division, reciprocation

fraction

fraction is a Python module that is designed for fractional values numerator/denominator

Installation

Easy to install

$ sudo pip install Fraction

Usage

>>> from fraction import Fraction

Creates a fraction equal to 0/1

>>> def_fraction = Fraction()

Creates a fraction equal to 3/10

>>> a = Fraction(3, 10)
>>> b = Fraction(1, 2)

# Get numerator/denominator
>>> a.numerator, a.denominator
(3, 10)

Computes reciprocal of fraction as Fraction object

>>> recip_a = Fraction.reciprocal(a)
>>> recip_a.numerator, recip_a.denominator
(10, 3)

Perform addition of Fraction objects (returns a Fraction object)

>>> sum_ab = a + b
>>> sum_ab.numerator, sum_ab.denominator
(4, 5)

Perform subtraction of Fraction objects (returns a Fraction object)

>>> diff_ab = a - b
>>> diff_ab.numerator, diff_ab.denominator
(-1, 5)

Perform multiplication of Fraction objects (returns a Fraction object)

>>> mul_ab = a * b
>>> mul_ab.numerator, mul_ab.denominator
(3, 20)

Perform div of Fraction objects (returns a Fraction object)

>>> div_ab = a / b
>>> div_ab.numerator, div_ab.denominator
(3, 5)

Comparison/Relational operations

Supports comparison operations [<, <=, >, >=, ==, !=] (returns boolean)

>>> a < b
True
>>> a == Fraction(7, 10)
False

For debugging

Supports str() and repr() built in objects methods

>>> a = Fraction()
>>> print a
0/1
>>> a
Fraction: 0/1
