In (info "(elisp) C Integer Types"):
* Prefer the Emacs-defined type `EMACS_INT' for representing values
converted to or from Emacs Lisp fixnums, as fixnum arithmetic is
based on `EMACS_INT'.
What does the "Emacs Lisp fixnum" mean here? I had searched the manual and web, but I didn't find anything useful. Can anybody help? Thanks.

It means just what the words say: a fixnum in Emacs Lisp. Fixnum is the
Lisp jargon for fixed-sized integers (as opposed to bignums, which are
practically unbounded -- Emacs Lisp doesn't have these).
