In Angular you can use the currency filter to format a number, like like this:
{{service.price | currency: "€ "}}
the standard output is
€ #,##0.00
How can the output be:
€ #.##0,00
(European notation)

Angular supports i18n Standard for location | globalization | internationalization. When it comes to number formatting Angular relies on $locale service and more specifically on the property NUMBER_FORMATS.
The currency symbol by itself will not change the numbering formatting unless you change the 'location'.
Here is the list of locations currently supported by angular:

Here is an example on how to support german locale:
<html ng-app>
<head>
<script src="angular.js"></script>
<script src="i18n/angular-locale_de-de.js"></script>
</head>
</html>
If you want to dig more into it you can search for NUMBER_FORMATS in any of the CDNs provided above and you will find what angular will use to format your numbers, this is an example:
"NUMBER_FORMATS": {
"CURRENCY_SYM": "\u20ac",
"DECIMAL_SEP": ",",
"GROUP_SEP": ".",
