I am trying to prepare a string in a controller and that to format a  
number as a currency in that string.

I can’t use number\_to\_currency as that only works in the view (as far as  
I can see)

The kind of thing I want to do is:

```auto
mystring = "Your budget is " + number_to_currency(budget.value)
```

any pointers to the right direction would be most welcome
