Also, if 1210 / 10 == 12.1 is your DESIRED and EXPECTED behavior for the
project you are working on, use the beauty of Ruby and simply alter
class Fixnum and be done with it.

class Fixnum
  def /(n)
    to_f / n
  end
end

Beats adding 0's all over the place :-)

(Note1: tested in Ruby 1.73, but should be backwards compatible.)
(Note2: for projects under your direct control only; such "fixes" will
break POLS for experienced Rubyists!!!)
