Hi list! I've tried adapting the following code for continued fractions: %https://tex.stackexchange.com/questions/73195/how-to-typeset-a-continued-fra... \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. Jairo :)
