# Part in KOMA adds enddots to numbers?

All is (typographically) fine with this MWE

\documentclass{scrbook}
\begin{document}
\tableofcontents
\chapter{chapter}
\chapter{chapter}
\end{document}


But as soon as I add \part to it the numbers are getting enddots:

\documentclass{scrbook}
\begin{document}
\tableofcontents
\part{part}
\chapter{chapter}
\chapter{chapter}
\end{document}


To get rid of the enddots one needs numbers=noenddot:

\documentclass[
numbers=noenddot
]{scrbook}
\begin{document}
\tableofcontents
\part{part}
\chapter{chapter}
\chapter{chapter}
\end{document}


What is the reason for putting dots to the numbers as soon as one has \part in the document?

From the KOMA script documentation (section '3.16. Structuring of Documents', page 95):

KOMA-Script decides, whether or not to set the period at the end of the numbers. The numbers consists in Arabic digits only, the period will be omitted. If there are alphabetic characters or roman numbers the period will always be set.

In your example, parts are numbered with roman numbers which is why a period is used if you include a part.

• strange behaviour but I will accept it. – LukasCB Feb 24 '18 at 22:44
• @LukasCB I seem to remember this is some kind of 'rule' in German texts, but I only found golatex.de/richtige-kapitelnummerierung-nach-duden-t14480.html and nothing official (my Rechtschreib-Duden didn't mention this, but I don't have a Duden style guide or DIN ... whatever ... at hand to check with them). – moewe Feb 25 '18 at 11:35
