define the helper in the controller, and use helper\_method maybe?

You can also directly instanciate a Helper object and call a method.

example with number\_to\_currency:

Object.new.extend(ActionView::Helpers::NumberHelper).number\_to\_currency(number, options)

but beware that is there are methods of other Helpers methods, they will fail.
