Thus, equation +numbers are printed by the <tt>\theequation</tt> command, and +section numbers by the <tt>\thesection</tt> command. +If you want to change the way such numbers are printed, for example, +change from arabic to Roman numerals, you need to redefine the +appropriate command, using the +<tt><a href="ltx-18.html">\renewcommand</a></tt> command. +<p> +As an example, to number equations in an appendix as <tt>A-1</tt>, +<tt>A-2</tt>, ... , use <pre> + <tt>\renewcommand{\theequation}{A-<a href="ltx-201.html">\arabic</a>{equation}}</tt></pre> +The second argument implies that the text produced by the renewed +<tt>\theequation</tt> command will be "A-" followed by the output from +the <tt>\arabic{equation}</tt> command, which is the value of the +equation counter, printed as an arabic number. +<p> +In <a href="lists.html">List Environments</a> the format for the +item labels is given by commands like <tt>\labelitemi</tt> and +<tt>\labelitemii</tt> (for the first two levels of the +<a href="ltx-250.html">Itemize Environment</a>), and like <tt>\labelenumi</tt> +(for the <a href="ltx-222.html">Enumerate Environment</a>), and these may +also be redefined. +<p> +There is an <a href="ltx-260.html#example">example</a> of manipulating such +counters in the discussion of the List Environment. +See also the discussions in the <a href="ltx-250.html">Itemize Environment</a> +and in the <a href="ltx-222.html#example">Enumerate Environment</a>. +<p> +You can force a change in the number produced by any of the counters. For +example, if you wanted to produce a single page numbered 13, you could use +<pre> + <tt><a href="ltx-310.html">\setcounter</a>{page}{13}</tt></pre> +A variety of commands for manipulating counters this way are given below. + +<H2>Related topics</H2> +<ul> +<li>Commands that manupulate counters +<ul> +<li><A href="ltx-195.html">\addtocounter</A> +<li><A href="ltx-271.html">\newcounter</A> +<li><A href="ltx-310.html">\setcounter</A> +<li><A href="ltx-338.html">\usecounter</A> +<li><A href="ltx-339.html">\value</A> +<li><a href="ltx-18.html">\renewcommand</a> +</ul> +<li>Commands that print the value of a counter in various formats +<ul> +<li><A href="ltx-201.html">\arabic</A> +<li><A href="ltx-199.html">\alph \Alph</A> +<li><A href="ltx-305.html">\roman \Roman</A> +<li><A href="ltx-230.html">\fnsymbol</A> +</ul> +<li>For some examples of usage in list environments, see +<ul> +<li><a href="ltx-260.html#example">List Enviroment</a> +<li><a href="ltx-250.html">Itemize Environment</a> +<li><a href="ltx-222.html">Enumerate Environment</a> +</ul> +</ul> +<hr> +See also <a href="ltx-141.html">Sectioning</a><br> +Return to <a href="ltx-2.html">LaTeX Table of Contents</a> +<hr> +<address> +Revised: Sheldon Green, 25 Oct 1995. +</address> +</body> +</html> |
