Indeed it seems like the alignment is good with \dfrac, but this does
not solve my problem, since I wish to also use fractions with
script-size or scriptscript-size (\xfrac, \xxfrac). The specific
formula I have is
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t

, if you plan to use such fractions in serious work, do read
the introduction of xfrac
(ftp://tug.ctan.org/pub/tex-archive/macros/latex/exptl/xfrac/doc/xfrac.pdf)
I think that the vigrule vs solidus argument also applies to ConTeXt's
definition.

{a}{b} (a+b)$
The a and b of the fraction is in text mode rather than math mode. On
the LaTeX end, there are two packages that provide such a feature:
nicefrac and xfrac.
Nicefrac ensures that the height of the fraction is not greater than
`M'. It is somewhat cleaver, and works correctly
