Changing style of unnumbered chapters in memoir

Question

The MWE below illustrates that while I can center numbered chapter headings, I cannot do so for unnumbered chapter headings:

\documentclass{memoir}
\renewcommand*{\printchaptername}{\centering}
\begin{document}
\chapter*{Unnumbered chapter}
\chapter{Numbered chapter}
\end{document}

What am I doing wrong?

Answer 1

Have a look at how the chapter headings are printed (p. 82). memoir makes a distinction here. For unnumbered chapters, you'd need this:

\documentclass{memoir}
\renewcommand*{\printchaptername}{\centering}
\renewcommand*{\printchapternonum}{\centering}
\begin{document}
\chapter*{Unnumbered chapter}
\chapter{Numbered chapter}
\end{document}
