Bertram,
So do like everyone else and extend the language to your liking ;-)
I have a small custom Rails app here which has the following in an 
Integer.rb file, under /lib :

class Integer
  def to_hours
    self / 3600
  end
end

Because I needed that (yes - just like that, no floating point division) 
and it wasn't in Ruby.
