[Rails] 123 * 3 => 123123123! But why?

[Joshua Muheim]

Hi all

I extended the Globalize Plugin the following way:

--------
module Globalize
  class Currency
    def conversion_rate
      code = Locale.active.currency_code
      rates = { :USD => 1,
                :CHF => 0.75,
                :EUR => 1.1,
                :GBP => 3.1
              }
      value = rates[code.to_sym]
      raise "No conversion rate found for currency '#{code}' 
(#{Locale.active.language.english_name})!" if value.nil?
      value
    end

    def dollar_part
      na? ? nil : cents / 100 / conversion_rate
    end

    def cent_part
      na? ? nil : cents % 100 / conversion_rate
    end
  end
end
--------

Sadly I get ugly results like

$99.00 # correct!
SFr. 132,0.00 # incorrect!
€ 90,0,00 # incorrect!

I don't know why Ruby concatenates the values and does not multiply 
them... How can I fix that?

Thanks for help. :-)
Greetings, Josh
