# No section numbering in scrbook

I am using the scrbook class.

In some chapters, I have sections so the elements therein get numbered x.y.z where x denotes the numbering of the chapter, y the one of the section and z the one of the specific element within the section.

However, I also have chapters without sections and I don't want to have a single section title for the whole chapter. If I just use no section, the elements in the content get numbered x.0.z since there is no section.

How can I get rid of the 0 for the chapters without section, so to have a numbering

x.1
x.2
...


therein?

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – user31729 Sep 6 '15 at 11:33
• With elements in the content you mean ... what? Subsections? Subsubsections? – user31729 Sep 6 '15 at 11:35

The zero section numbers can be omitted the following way, example for equation:

\renewcommand*{\theequation}{%
\ifnum\value{section}=0 %
\thechapter
\else
\thesection
\fi
.\arabic{equation}%
}

• There's no equation mentioned in the OP – user31729 Sep 6 '15 at 11:36
• @ChristianHupfer The question refers to elements. I assume this means figure, table, equation or whatever the document uses. Since I cannot provide definitions for infinite element types, equation is just an example. – Heiko Oberdiek Sep 6 '15 at 11:40
• @clemens Usually the section number already includes the chapter number. If the document uses a different layout, then the example needs to be adjusted, of course. – Heiko Oberdiek Sep 6 '15 at 11:41
