# Formats a +number+ into a currency string (e.g., $13.65). You
# can customize the format in the +options+ hash.
#
+ # The currency unit and number formatting of the current locale will be used
+ # unless otherwise specified in the provided options. No currency conversion
+ # is performed. If the user is given a way to change their locale, they will
+ # also be able to change the relative value of the currency displayed with
+ # this helper. If your application will ever support multiple locales, you
+ # may want to specify a constant <tt>:locale</tt> option or consider
+ # using a library capable of currency conversion.

# * <tt>:locale</tt> - Sets the locale to be used for formatting
