Bug in the latest beta: \frac

Bug in the latest beta: \frac

[Otared Kavian]

Hi Hans,

I just tried the new beta (ConTeXt  ver: 2015.03.28 16:30 MKIV beta  fmt: 2015.3.28  int: english/english)
It gives an error with the following minimal example:

\starttext
\startformula
\frac{2}{4}
\stopformula
\stoptext

The error message is:
\math_frac_command ->\cclf_mathfraction 
                                        {\mathfractionparameter \c!rule }\nu...
\math_fraction_inner_normal ...\math_frac_command 
                                                  {\usemathstyleparameter \m...
l.3 \frac{2}{4}


However using \over works fine, as in the following example:

\starttext
\startformula
{1 \over 2}
\stopformula
\stoptext

Best regards: OK

I confirm that $\frac12$ yields an error:


tex error       > error on line 2 in file frac.tex: ! Missing number, treated as zero
