Instance Method Details

#to_ruby_range(s) ⇒ Object

If the string contains a Ruby range definition (ie something like “93.0..94.5” or “56..72”), it will return the Range instance. Will return nil else.

The Ruby range returned (if any) will accept String or Numeric, ie (4..6).include?(“5”) will yield true.
