Hello David and Neil, Thank you for your information. I should have checked the mathml specification first. The following issue maybe is not very important, but as a MathML editor provider to companies, we know that customers are fussy. In order to highlight the residue, we usually wrap it with some kind of mark. See attached file. Is that feasible in MathML?

Yes, David is correct, but here's the correct markup (it's even simpler): <mlongdiv longdivstyle="shortstackedrightright"> <mn> 435,3</mn> <mn> 3 </mn> <mn> 1306</mn> <msgroup position="1" shift="-1"> <mn> 10</mn> <mn> 16</mn> <msrow position='-1'> <mn> 1,0</mn> </msrow> <mn> 1</mn> </msgroup> </mlongdiv> Neil On Thu, Nov 12, 2009 at 5:36 AM, David Carlisle <davidc@nag.co.uk<mailto:davidc@nag.co.uk>> wrote: > The whole list is automatically doubled if you omit the step of > writing the "auxiliary products".

Actually the mathml doesn't have any special markup for the stack of calculation so you can I think just use shortstackedrightright but omit the rows of the mlongdiv with mn corresponding to the products and the mlines to get the layout that you show. so something like <mlongdiv longdivstyle="shortstackedrightright"> <mn> 435,3</mn> <mn> 3 </mn> <mn> 1306</mn> <msgroup position="2" shift="-1"> <msgroup> <mn> 10</mn> </msgroup> <msgroup> <mn> 16</mn> <mn> 1,0</mn> </msgroup> <msgroup position='-1'> <mn> 1</mn> </msgroup> </msgroup> </mlongdiv> (untested as I haven't got an implementation of this yet) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
