Hi, the output of \setupmathematics[ integral=nolimits, ] \starttext \startTEXpage[offset=2bp] $\displaystyle\int_0^1x^2\,dx=\frac{1}{3}$ \stopTEXpage \stoptext is attached. Clearly, the lower limit in the integral is not correctly placed. With hope of a quick fix, Mikael

one way to deal with this is setting options (but these can be different per font and i'm not sure yet how to support that) you can try if \mathnolimitsmode=3 works ok for you will work ok for you \startTEXpage[offset=2bp] $\mathnolimitsmode0 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode1 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode2 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode3 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode4 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode2000 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par \stopTEXpage ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

you can try if \mathnolimitsmode=3 works ok for you

will work ok for you

\startTEXpage[offset=2bp] $\mathnolimitsmode0 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode1 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode2 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode3 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode4 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par $\mathnolimitsmode2000 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par \stopTEXpage

Oh, that sounds bad if it is in the fonts (I don't understand, it seemed to work fine with lmodern, stixtwo, lucidaot, ... just before, has something changed recently?) Two related questions: 1) This \mathnolimitsmode does not seem to have any effect in a \startformula \stopformula. 2) Could one set this globally (both inline and displayed formulas) in a document? /Mikael

well, then always enable mode 3 ... the default to mode 0 is because fonts can have kerns to deal with this but anyone can choose his/her preference ... as said, i'm nto sure hot to deal with it in context (as i might as well decide to add proper kerns to these fonts at runtime)

you can try something \appendtoks ... \to \everymathematics (i might cook up some more granularity in the future - i have some ideas about it - but that will then be experimental for a while) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

New subject: special book layout problem in ConTeXt

Dear ConText Hepers, I'm not sure I'm writing at the good email adress, or even the good place; but sorry, I didn't find any online forum or othr hep centers, so I try. Please tell me if I have to write to someone else. I'd like to edit a thesis (so, as a book), with the text only on even pages, and tables and figure only on odd pages, in front of the paragraph wich comment them. I try to do this automatically by writing the text, make a reference to the figure in the paragraph, and then the layout appears correctly... I have the impression this is possible to do in ConText, but I havn't find how yet. Is it possibel to force, in the setups, the text to be on the right pages, and the figures on the left pages? Thank you very much in advance All the best Nicolas Mondon -- /Nicolas Mondon catalogue, écoutes, concerts : http://n.mondon.free.fr/ /

This is the right place for your questions.

If the figures/tables should appear before the text you want on a even (left side) page while the text would appear only on odd (right side) pages. A few questions remain before a certain answer can be given, e.g. should the left page be empty when there are no figures/tables for the following right page and should the float appear at the same vertical position as the reference.

I have the impression this is possible to do in ConText, but I havn't find how yet. Is it possibel to force, in the setups, the text to be on the right pages, and the figures on the left pages?

There is no easy solution for this yet and it also depends on your requirements mentioned above. The easiest way to achieve such a layout is to to increase the paper width to twice the normal layout and use the left half for a very big margin area where you can place the tables/graphics. In a first step you create a normal document with this unusual layout. Afterwards you split each page in half and create two separate pages from one single page which can be done with a loop (can be done theoretically with the imposition mechanism but a separate document is easier).

New subject: special book layout problem in ConTeXt

Thank you Wolfgang for your answer. So, yes the figures/tables should appear before the text on a even (left side) page while the text would appear only on odd (right side) pages. The left page should be empty when there are no figures/tables for the following right page, and the float doesn't have to appear strictly at the same vertical position as the reference, but as possible only. Specially beacause, it may have several references in only one paragraph for exemple on the right page, and so the figure should appear in the right order on the left page, but couldn't be exactly at the same height. Also, if there are too many references in on right page, the figures which can't fit the left page should go on the top od the next left page... It's possible that my answer change the proposition you made at the end of your message. Nevertherless, there is some thing in your last paragrph which is not clear for me : " Afterwards you split each page in half and create two separate pages from one single page which can be done with a loop (can be done theoretically with the imposition mechanism but a separate document is easier)."
