Hi Wolfgang,
I'm reading this thread and I'm interested because I type a lot of text with mathematical formulas.
In fact, I find that \dfrac{} creates unsightly leading space and that \frac{} is too small. What is the difference between \frac{} and \tfrac{} ?

\frac switches the math style while \tfrac (textstyle), \dfrac (displaystyle) and \sfrac (scriptstyle) enforce a certain style.

%%%% begin example
\startbuffer[frac]
\frac{1}{2} + \dfrac{1}{2} - \tfrac{1}{2} + \sfrac{1}{2}
\stopbuffer

\starttext

\startformula
\getbuffer[frac]
\stopformula

\m{\getbuffer[frac]}

\startformula
\frac
{\getbuffer[frac]}
{\getbuffer[frac]}
\stopformula

\m{\frac
{\getbuffer[frac]}
{\getbuffer[frac]}}

\stoptext
%%%% end example

Wolfgang
