Hi,
In plain TeX,
$$\smash{\sum_0^n}$$
is set in \displaystyle, just like
$$\smash{\sum_0^n}$$
However, ConTeXt
\starttext
$$\smash{\sum^0_n}$$
\stoptext
outputs the above in \textstyle, whereas
\starttext
$$\sum^0_n$$
\stoptext
is in (of course(?)) \displaystyle.
Is this difference intentional?
Thanks.
Jim

Thanks for reporting. I don't think it is intentional. (Can you show your
real world example where \smash is needed? It seems to not really be used
in any macro in ConTeXt.)
/Mikael
PS $$ is not meant to be used in ConTeXt. If you want inline math in
display style, use \dm {}, and if you want displayed formulas in display
style, use \startformula \stopformula.

At the risk of citing an example using a deprecated feature, in
https://wiki.contextgarden.net/Tables/Deprecated/Table
the following example is shown:
\starttable[|M|c|]
\HL
\VL \VL a \VL \AR
\DC \DL[1] \DR
\VL \smash{\displaystyle\sum_0^N} \VL b \VL \AR
\DC \DL[1] \DR
\VL \VL c \VL \AR
\HL
\stoptable
Without \smash{}, the second row is higher than (presumably) whomever wrote
the example wanted. I can imagine someone wanting to do something like
that in another type of table, even using a non-deprecated type of table.
(I added \displaystyle to the example yesterday to make it do what the
example's author intended.)

Yeah... as a very-long-time plain TeX user, old habits die hard (and I am
not using any math in my current main use of ConTeXt).
The main reason for using $$ in my report was because that is what is in
the wiki page. (And the issue is still there with \startformula and
\stopformula anyway.)
Cheers.

Thanks Hans, that fixes that up nicely.
(And it is always nice to see a fix which actually makes the codebase (a
bit) shorter.

Thanks Hans,
I took the liberty of adding that to the (deprecated) TaBlE page for the
benefit of anyone trying to undeprecate themselves.
