Freemarker, a popular template engine, offers flexibility in formatting data for various purposes, including currency representation. However, sometimes standard settings may not suffice, especially when dealing with specific localization requirements such as German currency formatting. In this article, we’ll explore a custom function created in Freemarker to meet German currency formatting standards.
