Decimal separator
The langconfig file is an important file in a language pack, dealing with all the configuration parameters of that language, including the decimal separator.

If a language pack uses a comma (,) as a decimal separator, it must use a semicolon (;) as a list separator, or serious errors might happen.
Problems with language packs using a decimal comma
It is not uncommon for Moodle users with a language pack that has a comma used as a decimal separator to experience problems when using formulas copied from the Moodle English online and built-in documentation.
Gradebook problems
The Gradebook calculations might use "=average(item1, item2, item3, item4, item5, item6)" which is easy to understand and use in English, but a teacher with (for example) the international spanish (es) language pack will strugle until he/she realizes that this formula should be changed to "=average(item1; item2; item3; item4; item5; item6)"
Problem fixing
A Moodle adminer who uses a language pack with a decimal comma must check the langconfig file and make shure that the decsep, listsep and thounsandsep characters are properly set for the language or use the Language customization to fix his/her server.
