Question

How to format my number with the helper number_to_currency, but show it without the currency symbol ($, R$, etc)?
Ex.:

$ 500,78  -> Not what i want
  500,78  -> Format i desire

Answer 1

Try using it with the :unit option set to empty string.

number_to_currency(1234567890.50, :unit => "")
