What's the opposite of chr() in Ruby?

Question

In many languages there\'s a pair of functions, chr() and ord(), which convert between numbers and character values. In some languages, ord()

Answer 1

I'm writing code for 1.8.6 and 1.9.3 and I couldn't get any of these solutions to work in both environments :(

However, I came across another solution: http://smajnr.net/2009/12/ruby-1-8-nomethoderror-undefined-method-ord-for-string.html

That didn't work for me either but I adapted it for my use:

unless "".respond_to?(:ord)
  class Fixnum
    def ord
      return self
    end
  end
end

Having done that, then the following will work in both environments

'A'[0].ord
