Hi,
I want to write:
$0,00\stackrel{\smallfrown}{4}$
like latex [https://tex.stackexchange.com/questions/39225/differences-between-stackrel-and-stackbin]
but context LMTX does not recognize stackrel
What can I do?
Thanks in advance,
Xavier
PS: Please CCme

\stackrel is defined in context (with almost the same definition as latex). You get an error because \smallfrown is not defined.

Interesting, but I think that the OP wanted to use \frown as an accent,
Aditya

\definesystemconstant {base}

Nice with offset=auto. It is not clear to me what the intent/meaning
is of the original example, but one can also try the 23DC (can extend
as \overparent):
\definemathtopaccent[topfake][frowned]["2322]
\definemathtopaccent[topfake][Frowned]["23DC]
\starttext
$ x + \frowned{4} = 10$
$ x + \Frowned{4} = 10$
$ x + \Frowned{4444} = 10$
$ x + \overparent{4} = 10$
$ x + \overparent{4444} = 10$
\stoptext

I guess, some book/paper somewhere introduced it as an accent, and now others follow the same style.

and then someone (likely non-math-aware) able to make a case for getting
it into unicode where it disappears in the avelange of weird symbols
