Some symbols of mathematical calculus missing?

Some symbols of mathematical calculus missing?

[Tomas Kisela]

Hi all,

I need to typeset some equations and I found out that these commands are undefined or don't work correctly (ver: 2009.04.17 19:32 MKIV):

\iint, \iiint, etc.
\oint, \oiint, etc.
\nabla

What is the prefered way of typesetting those symbols? (e.g. \mathop{\int \!\!\! \int} or something like that?)
Is there a website or a pdf-file dealing with mathematical symbols in ConTeXt?

Thanks
Tomas

I don't know why \iint and \iint are failing. \oiint is not defined in 
mkii, so there is no definition in mkiv. \oint is working here.

Change the following in math-vfu

diff --git a/math-vfu.lua b/math-vfu.lua

It is more complicated, since you need to adjust for limits. These are 
defined in math-ini.mkiv, but for some reason the definitions are not 
kicking in.

Thanks for nabla.
I can handle the commands for multiple integrals by myself in the way I sketched before. 

Contour integral \oint is working but not correctly in my case. This code:

\starttext
\startformula
\oint\limits_{\partial S} \vec{F}\cdot{\rm d}\vec{l}=\mathop{\int\!\!\!\int}\limits_{\bs S\phantom{M}} \vec{\nabla} \times \vec{F}\cdot{\rm d}\vec{S}
\stopformula
\stoptext

gives the result in the attachment (I know I can typeset it by a combination of \circle and \int or something similar, my point is just to show the problem with \oint).

Thanks for help,
Best regards,
Tomas
