math functions

[billet]

Hi,

I would like to set the font used for math functions like \sin to be
the body font. Of course, it should go for scriptsize when used in
exponents.

I tried without success to define  \def\mfunction#1{{\tf\rm #1}} 
What is the conTeXt way to do this?

Thanks for your help,
Olivier

But they do that already, at least in the default font setup. Well,
you can try this:

   \def\mfuction#1%
     {\mathchoice
       {\hbox{\rm \tf #1}}
       {\hbox{\rm \tf #1}}
       {\hbox{\rm \tfx #1}}
       {\hbox{\rm \tfxx #1}}}

Cheers, Taco

$ grep '\\def\\mfunction' /usr/share/texmf/tex/context/base/*
/usr/share/texmf/tex/context/base/math-ini.tex:\def\mfunction#1{{\mr#1}}

Many thanks, that was what I was looking for.

Yes, I know. That definies does give me computer modern regular upright,
scaled properly.

Ok, I added thsi to math-ini:

%D Taco posted this solution as response to a mail by Olivier, so
%D let's integrate it here.

\def\setmathfunctionstyle#1% \rm \ss \tt
  {\def\mfunction##1% no families, just scaling a la text
     {\mathchoice
        {\hbox{\csname#1\endcsname\tf  ##1}}
        {\hbox{\csname#1\endcsname\tf  ##1}}
        {\hbox{\csname#1\endcsname\tfx ##1}}
        {\hbox{\csname#1\endcsname\tfxx##1}}}}

%D Usage:
%D
%D \starttyping
%D \setmathfunctionstyle\fontstyle % or {rm} or {ss} or ..
%D \rm test $\sin{(x^{\sin(x^{\sin(x)})})}$ test
%D \ss test $\sin{(x^{\sin(x^{\sin(x)})})}$ test
%D \tt test $\sin{(x^{\sin(x^{\sin(x)})})}$ test
%D \stoptyping

so, you can follow the style automatically
