def ordinalize
  ActiveSupport::Inflector.ordinalize(self)
end

Ordinalize turns a number into an ordinal string used to denote the position in an ordered sequence such as 1st, 2nd, 3rd, 4th.

1.ordinalize     # => "1st"
2.ordinalize     # => "2nd"
1002.ordinalize  # => "1002nd"
1003.ordinalize  # => "1003rd"
-11.ordinalize   # => "-11th"
-1001.ordinalize # => "-1001st"
