How to extract the sign of an integer in Ruby?

Question

I need a function which returns/prints the sign on an integer. So far I came up with this:

def extract_sign(integer)
  integer >= 0 ? \'+\' : \'-\'
end
         


        

Answer 1

Ruby doesn't have a built in sign function like Javascript. Here's a thread that explains more http://www.ruby-forum.com/topic/141216

Your approach looks correct.
