I am using article class, and by default, the numbers of the sections, subsections appear like 1 section, 2 section in time I want them to appear like 1. section, 2. section (with dots).

I have redefined the format of my section, subsection, etc. as follows:


because I wanted . after the number of the section and the subsection. Fortunately, I got the format that I want, but now I have another problem, when I use the cross-reference to the section or the subsection, I got extra . after the reference, like: as we have seen in section 1.., or section 2.. it is unwanted. How can I get rid of this extra .? Is there anyway to change or redefine the appearance of the \ref?

My answer to can i change refs output can be adjusted for this:






See section~\ref{test} and subsection~\ref{subtest} and subsubsection~\ref{subsubtest}!


Note that this is a little bit of a hack.

You could also adjust the sectioning commands using titlesec instead.

This is not the correct way to do that simple thing. It's true that titlesec can be used, but the formatting of the (sub)section number is under the control of \@seccntformat. – egreg Jul 6 '11 at 9:31
@egreg: I thought that there should be a better way to do it. Please also see the original question (this is a follow-up) Can I change \ref's output? and consider answering it as well. Thanks! – Martin Scharrer Jul 6 '11 at 9:38
That is correct. – egreg Jul 6 '11 at 9:48
Thank you Martin. It works. – Mara Jul 6 '11 at 14:04
@Mara: actually egreg's solution is better. Give it a try. – Martin Scharrer Jul 6 '11 at 14:06

See the relevant UK TUG FAQ

\renewcommand{\@seccntformat}[1]{\csname the#1\endcsname.\quad}

use the class scrartcl instead. It has an optional argument for this:
