No multiplier option for Field::Number.

Created by: tristandunn

The customizing dashboards documentation mentions using a multiplier to display a currency value stored in cents. As far as I can tell that's not actually possible.

I'm guessing it should be something close to the code below. Unsure if it should attempt any casting or type checking though.

module Administrate
  module Field
    class Number < Field::Base
      def to_s
        if data.nil?
          "-"
        else
          format_string % value
        end
      end

      protected

      def value
        data * options.fetch(:multiplier, 1)
      end
    end
  end
end
