To avoid floating point errors, you might as well just do : (self * 1.0).round.(x) or self.to_f.round.(x) And wouldn't that be a patch to class Integer, as Float already has .round working fine? Or am I missing something ?:-/ -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
