TAG REFERENCE
<currency:format>
Given a price, usually in decimal form, format returns a formatted price using the various options in Locale::Currency::Format.
<currency:format>
<currency:price>10.9</currency:price>
</currency:format> # prints &#x0024;10.50
The format tag has three available attributes to control the output:
- code
-
This is the 3 letter currency code used to specify the currency in use. The
codeattribute can also be specified using a child tag instead:<currency:format> <currency:code>USD</currency:code> </currency:format>USDis used as the default if no currency code is specified. SeeLocale::Currency::FormatandLocale::Currenctyfor all of the available currency codes.If
Locale::Currencyis installed, it will verify the 3 letter code is actually a valid currency code and die if it is not, otherwise it simply checks that the code conforms to:/^[A-Z]{3}$/ - options
-
This is a string containing the formatting options to be used to specify the desired output format. The
optionsattribute can also be specified using a child tag instead:<currency:format> <currency:options>FMT_STANDARD | FMT_NOZEROS</currency:options> </currency:format>FMT_SYMBOLis used as the default if no options are specified. SeeLocale::Currency::Formatfor all of the available format options. - price
-
This is the price to be formatted. While it can be passed as an attribute, the more common usage will be as a child tag:
<currency:format> <currency:price>19.95</currency:price> </currency:format>You can also next a
converttag inside ofpriceto format the results of a currency conversion:<convert:price> <currency:convert from="USD|CAD|JPY|..." price="10.95" to="CAD|JPY|..."> <currency:from></currency:from> <currency:price</currency:price> <currency:to></currency:to> </currency:convert> </convert:price>
