I have been trying out the newish
\setupmathradical[sqrt][alternative=mp], which has been very nice
because of the fine control over the radical sign.
I've noticed that it crunches the denominator in \sqrt{a\over b}
For example:
\starttext
\placeformula\startformula
\sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}}
\stopformula
\setupmathradical[sqrt][alternative=mp]
\placeformula\startformula
\sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}}
\stopformula
\stoptext
In the first line, the fractions come out fine. In the second line, the
first k\over m has a small, inline-math m in the denominator but a
display-math k in the numerator. The second sqrt is fine.
Is the problem that my plain-TeX habits, from decades using \over,
should be over, and that \frac is the recommended way?
indeed. this is what (sort of) happens in case of a plugged in renderer:
\sqrt{#1} -> ...\mathstylehbox{#1}... -> ...\hbox{\stylecommand #1}...
when #a = a \over b the style gets applied to the a only as \over
creates two (pseudo) groups i.e. the \over isolates a and b
> \sqrt{{k\over m}}\quad \sqrt{\displaystyle{k\over m}}
would work ok
