Getting a currency format pattern from AngularJS filter

Question

I'm interested in creating a filter that would accept an amount, ISO 4217 currency code, and fraction size, and return the amount in that format. I noticed that AngularJS has goog.i18n.currency.getGlobalCurrencyPattern in i18n/closure/currencySymbols.js, but I'm relatively new to Angular and not sure if it is possible to use it?

Answer 1

The currency pattern and symbols are just that. It determines how to display a number. It will not convert it from XXX to XXX. You will have to do the converting part based on the current conversion rates.

As far as using the built-in currency formatting, there are multiple ways: in the template, in the code.

In the template:

<div>{{myCurrencyValue | currency:'XXX'}}</div>

In the code:

var formatted = $filter('currency')(myCurrencyValue, 'XXX')

In both cases, 'XXX' is optional [and is symbol] and will use the default currency for current locale

UPDATE

Example with ISO 4217 codes using custom filter: http://jsfiddle.net/TheSharpieOne/N7YuP/3/

Note: ISO 4217 doesn't dictate the currency symbols, I used this for symbol reference and mapped them.
