b-fractions 0.0.2

This module enables you to use fractions within your program

BASIC FRACTIONS MODULE (VERSION 0.0.1)

Developed by Md Mahdi Tajwar Raeed, Bangladesh (August, 2022)

This is a simple module that let's you use fractions in Python for various purposes (e.g. calculations, or displaying data in a cleaner way)

Features

• Convert mixed fractions to improper fractions and vice versa
• Convert fractions to decimals
• Simplify fractions
• Add, subtract, multiply, divide fractions (result comes out simplified)

Reminder

• A mixed fraction is a number that contains a whole number along with a rational number (fraction). For example: 2 1/3
• An improper fraction is a rational number which has a greater numerator than denominator.
• A proper fraction is a rational number which has a smaller numerator than denominator. It can't be converted into a mixed fraction.

Important Note

Not all functions support mixed fractions; use proper/improper fractions unless it allows mixed fractions (this will be elaborated below).

Usage

Initialise the module by writing "from b_fractions import *

This module contains 2 classes:

• normalFraction (for proper/improper fractions)
• mixedFraction (for mixed fractions)

The normalFraction class takes 2 values: Numerator and Denominator (e.g. 2/3)
The mixedFraction class takes 3 values: Whole number, Numerator and Denominator (e.g. 2 1/3)
Here are examples of how to initialise a normal fraction and a mixed fraction:

• fraction_1 = normalFraction (2, 3)
  2/3
• fraction_2 = mixedFraction (2, 1, 3)
  2 1/3
  In order to print a fraction to the screen, write:
  fraction_1.show()

IN ORDER TO ACCESS A NUMERATOR OR DENOMINATOR INDIVIDUALLY, WRITE:

• fraction_1.nr (for numerator)
• fraction_1.dr (for denominator)
• fraction_1.w (for whole number if it is a mixed fraction)

Functions

• The function "normalfraction_to_mixed" takes a single improper fraction object and returns a mixed fraction object.
  fraction_3 = normalfraction_to_mixed(fraction_1)

• The function "mixedfraction_to_normal" takes a single mixed fraction object and returns an improper fraction object.
  fraction_4 = mixedfraction_to_normal(fraction_2)

• The function "normalfraction_to_decimal" takes a single normal fraction object and returns it in decimal form.
  num1 = normalfraction_to_decimal(fraction_2)

• The function "mixedfraction_to_decimal" takes a single mixed fraction object and returns it in decimal form.
  num2 = mixedfraction_to_decimal(fraction_2)

• The function "addition" adds 2 IMPROPER/PROPER fractions (doesn't work with mixed fractions). It takes in 2 values.
  fraction_5 = addition(fraction_1, fraction_4)

• The function "subtraction" subtracts the first IMPROPER/PROPER fraction by the second one (doesn't work with mixed fractions). It takes in 2 values.
  fraction_6 = subtraction(fraction_1, fraction_4)

• The function "multiplication" multiplies 2 IMPROPER/PROPER fractions (doesn't work with mixed fractions). It takes in 2 values.
  fraction_7 = multiplication(fraction_5, fraction_6)

• The function "division" divides the first IMPROPER/PROPER fraction by the second one (doesn't work with mixed fractions). It takes in 2 values.
  fraction_8 = multiplication(fraction_7, fraction_6)

• The function "comparison" takes in 2 values. It returns 1 if the first PROPER/IMPROPER fraction is greater than the second, and 0 otherwise.
  num3 = comparison(fraction_7, fraction_8)

Tip

If you need to add/subtract/multiply/divide 2 MIXED fractions, then simply convert them into improper fractions by using the function "mixedfraction_to_normal". Now you can use these for calculations.

Sample program

from b_fractions import *
f1 = normalFraction(3, 4)
f2 = normalFraction(3, 4)
f3 = addition(f1, f2)
f3.show()
Result: 3/2
