In page 90 of Grätzer's More Math into LaTeX (5th edition), he uses a \newcommand command to define a binary mathematical operation as follows:

\newcommand{\circwithdot}{\mathbin{\rlap{$\mspace{2mu}\cdot$}\hbox{$\circ$}}}

What is the use of the \hbox here? Why does not he use the \mbox command? Are they the same in this case?

»Why does not he use the \mbox command?« Because the author made a mistake here. In LaTeX \mbox should be preferred over \hbox, see the linked threads above. – Henri Menke Jul 16 '17 at 02:44

While the link is about the differences between \hbox and \mbox, it doesn't really answer the question. – egreg Jul 16 '17 at 08:42
