I've tried adapting the following code for continued fractions: %https://tex.stackexchange.com/questions/73195/how-to-typeset-a-continued-fraction-in-the-following-format \documentclass{article}\usepackage{amsmath} \begin{document}\newcommand*{\cofrac}[2]{% {% \rlap{$\dfrac{1}{\phantom{#1}}$}% \genfrac{}{}{0pt}{0}{}{#1+#2}% }%}\[ a_0 + \cofrac{a_1}{ \cofrac{a_2}{ \cofrac{a_3}{ \genfrac{}{}{0pt}{0}{}{\ddots} }}}\]\end{document} As I could read from the mailing list, ConTeXt no longer supports \genfrac, so I've tried the following using \definemathfraction \definemathfraction[gefrac][cfrac] \setupmathfraction[gefrac][rule=no] \def\cofrac#1#2{% {% \rlap{\cfrac{1}{\displaystyle\phantom{#1}}}% \gefrac{}{\displaystyle\gefrac{#1+}{}#2}% }% } \def\cofracnorule#1#2{% {% \rlap{\gefrac{\displaystyle\phantom{1}}{\displaystyle\phantom{#1}}}% \gefrac{}{\displaystyle\gefrac{#1}{}#2}% }% } \def\endfrac#1{\cofracnorule{#1}{\phantom{1}}} \startTEXpage \startplacefigure[location=force,number=no] \externalfigure[cofrac.png] \stopplacefigure \startformula \alpha + \cofrac{\alpha'}{\cofrac{\alpha''}{\cofrac{\alpha'''}{{\endfrac{\ddots}}}}} \frac{1}{\alpha'''} \stopformula \stopTEXpage Mmm, superscripts and fraction rules superpose, so indeed something is wrong. Any ideas or references to a better result? I've attached the expected result (it's from Legendre's Théorie des nombres) and a normal fraction for comparison. Thank you very much.

There is a manual about math but it's not complete (of course, otherwise there's nothing to complain and we have to protect our reputation of not having manuals). But ... contributions (examples etc, as I can blabla the rest) are welcome.

I'm seeing it's more illustrating about subjects as integrals and other stuff, tho. Reading the mailing list, I realized there's a simplecommand key for matrices, among other nice things which maybe should be... if not documented, at least mentioned. > we have to protect our reputation of not > having manuals lmao But ... contributions (examples etc, as I can blabla > the rest) are welcome. > I'll take note of that.
