Extend the number class

Question

I want to extend the number class to have instance functions such as odd and even so I can do something like this:

2.odd() => false
         


        

Answer 1

I'd like to point out that that is already available in the numbers class.

Just use the boolean methods, odd? and even?

2.odd?
=> false

2.even?
=> true

Hope this helps.

No need to create a new class, it already exists in the numbers class.
