Hi all, I want to typeset double integral with subscript beneath the integral symbol. I found \unic@dblint for double integral, and used the usual \limits in plain tex: \unic@dblint\limits_{\startsubstack x \ge 0,\NR 0 \le y \le T\stopsubstack} The subscript did go below the integral, but the two integral symbols are separate from each other. Any tips? Thanks a lot! Shenchen

$$ \mathop{\unic@dblint}\limits_ {\startsubstack x \ge 0,\NR 0 \le y \le \stopsubstack} $$ (it should be possible to do this more elegant, though)

\iint\limits should work correctly. It is based on the same macro in amsmath. If you always need \limits, I can provide an option for \displaylimits or \nolimits after int, iint, and iiint. I did not know about unic@dblint, and it looks horrible (\int\!\!\!\int). This should be replaced by \iint and triint should be replaced by iiint. Aditya
I am using "ConTeXt ver: 2007.01.12", and \iint is not defined even when
newmat is imported. Taco's tip worked.
As I tried on live.contextgarden.net, which is running the latest ConTeXt,
\iint\limits_{...} works as intended.
Thank you.

They were added pretty recently. You can either update your context, or if you do not want to do that, add the following in your environment file (copied from math-tex.tex). %D More integrals (AM): \def\dointkern{\mkern-6mu\mathchoice{\mkern-3mu}{}{}{}} \definemathcommand [iint] {\repeatintegral\plusone } \definemathcommand [iiint] {\repeatintegral\plustwo } \definemathcommand [iiiint] {\repeatintegral\plusthree} \def\repeatintegral#1% {\scratchtoks\emptytoks \let\dointlimits\nolimits \dorecurse{#1}{\appendtoks \intop \dointkern \to \scratchtoks} \appendtoks \intop \dointlimits \to \scratchtoks \edef\dodorepeatintegral{\the\scratchtoks}% \futurelet\next\dorepeatintegral} %D If the \type{\limits} option is used after \type{\iint}, use %D \type{\mathop} and fudge the left hand space a bit to make the %D subscript visually centered. \def\dorepeatintegral {\ifx\next\limits \dointlimitcorrection \else \ifx\next\displaylimits \dointlimitcorrection \fi\fi \dodorepeatintegral} \def\dointlimitcorrection {\mkern-7mu\mathchoice{\mkern-2mu}{}{}{}% \mathop\bgroup \mkern7mu\mathchoice{\mkern2mu}{}{}{}% \let\dointlimits\egroup} Aditya
