The formatter expansion comes with two options that can be used in the number_format placeholders.


Changes the used locale for the format. Depending on what locale is used does the resulting format look different.
For example would de:CH display 1234 as 1'234 while en:US displays it as 1,234.

This defaults to en:US
Check the locales page for all available codes.


This option allows you to set the format used in the placeholder.
Please check the Javadoc about DecimalFormat for more information.
