Fraction Math in Every Language

Welcome to the Fraction Math page! Here, you’ll find a description of the project as well as a list of sample programs written in various languages.

Description

Languages like python have built-in utilities or functions for working with fractions. Many of these fractions functions follow a similar pattern across programming languages: takes a numerator and a denomenator as an attribute. Perform basic arithmatic and relational operations with operator overloading.

Requirements

In general, a fractions library should perform the following:

  1. Perform arithmatic operation like multiplications, addition etc.
  2. Give output for relational operations like >=, >, == etc.

More specifically, begin with creating object instance of fraction class with two attributes: numerator and denomenator.Using operator overloading feature of langauge implement basic arithmatic and relational operaions.

For instance ./fraction-math "6/2" "+" "1/4" would output 13/4

In addition, there should be some error handling for situations where the user doesn’t supply any input.

Testing

Some tests for your program are:

Description Input Output
No Input   “Usage: ./fraction-math operand1 operator operand2”
Empty Input ”” “Usage: ./fraction-math operand1 operator operand2”
Sample Input: 2/3 + 4/5 22/15
Sample Input: 2/3 * 4/5 8/15
Sample Input: 2/3 - 4/5 -2/15
Sample Input: 2/3 / 4/5 5/6
Sample Input: 2/3 == 4/5 0
Sample Input: 2/3 > 4/5 0
Sample Input: 2/3 < 4/5 1
Sample Input: 2/3 >= 4/5 0
Sample Input: 2/3 <= 4/5 1
Sample Input: 2/3 != 4/5 1
