Or, for inline math, $\sqrt{1/3}$.
radicals are somewhat special to deal with:
- multidimensional delimiter
- vertical spacing inside
- horizontal spacing oustside
- anchoring degrees
- left and right radicals
- more consistent rules (char based)
- size dependent additional spacing (avoid clash)
- normalize size across formula
- lack of granularity in variants sizes
by now we have dealt with all of that (some not in the current release),
think of additional control in the engine, compensation for insufficient
opentype math features, companion fonts with more sizes
there will always be suboptimal cases but the average is ok (we put
radical - character kerning on hold because it is a lot of definitions)
and we don't want to add hard to fight heuristics
so to inline: in most cases the solution that Adirya suggests will work
out okay with respect toline spacing

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
