How can I change the section numbering style for only one chapter?

Question

I am currently doing this:

\chapter{A Chapter}
\renewcommand\thesection{\Roman{section}}

But it affects ALL following chapters. I want to change the style of only this particular chapter. Is there a way to do that? Or do I need to manually change back the next chapter?

Answer 1

Quick workaround: use your redefinition inside a group

\documentclass{book}

\begin{document}

\begingroup
\chapter{A Chapter}
\renewcommand\thesection{\Roman{section}}
\section{test}

\endgroup

\chapter{B Chapter}
\section{test}

\end{document}
