Hi.

At @item arith-error
  , in @appendix Standard Errors
  , lispref manual, the manual says,

The message is @samp{Arithmetic error}. This occurs when trying to perform
integer division by zero. @xref{Numeric Conversions}, and @xref{Arithmetic
Operations}.

http://git.savannah.gnu.org/cgit/emacs.git/tree/doc/lispref/errors.texi#n49

  , but I think latter @xref should be @pxref.

Thanks.
