A simple class modeling rational numbers in Ruby
This class isn't necessary, because there already is
Rational in Ruby which you should use instead of this one.
However, this code is created while working through J.B Rainsberger's The World's Best Intro to TDD (WBITDD).
WARNING: I mean it — Use Ruby's
Rational class instead.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
> gem install seasides_fraction
In your code
require 'seasides_rational to load the gem and then either use the class
include SeasidesRational and use class
RationalNumber without having to type the full name all the time.
An example from an
> irb -r seasides_rational 3.0.0 :001 > SeasidesRational::Fraction[2,3] + SeasidesRational::Fraction[7,11] => #<SeasidesRational::Fraction:0x00007ffb3385b138 @denominator=33, @numerator=43> 3.0.0 :002 > include SeasidesRational => Object 3.0.0 :003 > sum = Fraction[7,22] + Fraction[33,21] => #<SeasidesRational::Fraction:0x00007ffb33a24320 @denominator=154, @numerator=291> 3.0.0 :004 > sum.to_s => "291 / 154"
After checking out the repo, run
