Fractions and binomial inlined in text ($n \choose \frac{n}2$): Parentheses not scaled

Fractions and binomial inlined in text ($n \choose \frac{n}2$): Parentheses not scaled

Dear ConTeXt folks,


using the following minimal example

        \starttext
        Using \type{\choose} in text $n \choose \frac{n}2$.
        
        \startformula
        n \choose \frac{n}2
        \stopformula
        
        \CONTEXT\ \contextmark\ \contextversion\ with \texenginename\
        \texengineversion
        \stoptext

the parentheses of the binomial in the text or too short. I guess this
is because the parentheses are not scaled when inlined and that this is
also a TeX limitation and therefore expected?

Thanks,

Paul

Instead if \choose you can use \binom which is the recommended way in context.

The \dbinom command sets the content in display style while \tbinom use textstyle.

\starttext

Using \tex{binom} in text $\binom{n}{\frac{n}{2}}$.

Using \tex{dbinom} in text $\dbinom{n}{\frac{n}{2}}$.

Using \tex{tbinom} in text $\tbinom{n}{\frac{n}{2}}$.

\startformula
\binom{n}{\frac{n}{2}}
\stopformula

\stoptext

Wolfgang

As always that did the trick. Thank you a lot Wolfgang and Dalyoung!


Thanks,
