| <h3>I want to use a binary operator (like <KBD><B>union</B></KBD> or <KBD><B>otimes</B></KBD>) |
| as a large operator (like <KBD><B>int</B></KBD> or <KBD><B>sum</B></KBD>). How can I do that?</h3> |
| <P>You have to define the symbol you want to use as a user-defined |
| symbol first. See <A HREF="012.html">FAQ #012</A> for instructions; |
| most of the symbols used by <I>Math</I> are part of the StarMath |
| font.</P> |
| <P>Let's say you have defined the union symbol as the user-defined |
| symbol <KBD>%union</KBD>. You can then enter for example</P> |
| <PRE STYLE="margin-bottom: 0.5cm">oper%union from i in I A_i</PRE><P> |
| in order to typeset the formula</P> |
| <P><IMG SRC="006a.gif" NAME="Objekt1" ALIGN="middle" HSPACE=8 WIDTH=47 HEIGHT=32 BORDER=0/></P> |
| <p><em>Note</em>: In build 633 this doesn't work if there is a space before |
| <kbd>%union</kbd> (this is a bug in the parser). |
| <P>Any user-defined symbol can be used as a large operator if it is |
| preceded with<KBD> oper </KBD>as in the example.</P> |
