Continuing my recent theme of finding glyphs too low or too high:
The \pm symbol looks like it is set too low, in MkIV.
\setuppagenumbering[location=]
\starttext
$\pm2$
\stoptext
The minus part of the sign lies below the baseline, which looks odd
relative to the horizontal stroke of the "2."
In MkII it is fine, as is the equivalent latex or plain tex (using
LatinModern).
I don't know whether the problem lis in the font metrics or in the
positioning by MkIV, because I haven't yet been able to convince tex,
latex, lualatex, or luatex to use the same font (LM math).
In MkIV, the font is (from pdffonts):
NSOXNN+LatinModernMath-Regular CID Type 0C Identity-H
Can anyone confirm the problem?

I can confirm that it is too low in latest standalone. It looks OK at
http://live.contextgarden.net/, though.
I can also add that \surd is way too low in latest standalone (and
only a bit to low in mkiv on http://live.contextgarden.net/, and OK in
mkii on http://live.contextgarden.net/).
\setuppagenumbering[location=]
\starttext
$\pm2$ and $\surd(1+2)$.
\stoptext

Hi Hans,
Thanks for your attention to the issue pointed out by Sanjoy.

Yes this is the case in recent versions of mkiv, but in Plain TeX and mkii this is not the case: there the minus sign in \pm is aligned with the baseline.
I agree with Sanjoy and Mikael to say that it the minus sign in \pm should be aligned with the baseline: however I don’t know if this can be easily achieved.
Best regards: OK

so how about \mp then ...

the + aligns on the math axis so one can argue if the type-one variant
is ok ... so we would need a smaller (less height) + then which would
look visually weird
(all can be achieved ... but the idea of lm/gyre fonts is to provide an
acceptable consistent set ... at some point we can think of variants -
or maybe the fonts have a variant already)

Plain TeX doesn't align the plus/minus to the math axis. Rather, the
minus is aligned to the baseline, and the horizontal stroke of the plus
is above the baseline. I agree that it looks a bit strange with the
horizontal stroke of the plus sign not aligned with the horizontal
stroke of the plus/minus. Bt it looks even more jarring to have the
minus below the baseline, because the baseline is such a strong visual
line.
I don't think I've ever the minus below the baseline in a math book, and
it looks very wrong to my eye.
Pagella looks worse than the others, because it has a vertical gap
between the minus and the plus sign, so the depth below the baseline is
even larger.

I realize that it's not a ConTeXt problem, but is there a ConTeXt
workaround? Or better to go to the TeX guts and compute the depth of
the box, then use \raise{}?

Sanjoy,
the following borrows the \pm sign from Asana (which also should be
like palatino), which looks more "normal".
% Start example
\definefallbackfamily[mainface][math][Asana Math]
[range={00B1-00B1}]
\definefontfamily[mainface][serif][Tex Gyre Pagella]
\definefontfamily[mainface][math][Tex Gyre Pagella Math]
\starttext
\switchtobodyfont[pagella] Hello $\int x \pm 2 + a $\par
\switchtobodyfont[asana] Hello $\int x \pm 2 + a $\par
\switchtobodyfont[mainface] Hello $\int x \pm 2 + a $\par
\stoptext
% Stop example
I guess one could do this for the other signs one don't like in TeX
Gyre Pagella Math...

Hi,
This is a good trick to know, especially if one combines \pm and \mp as in the counter-example given by Hans:
% Start example
\definefallbackfamily[mainface][math][Asana Math]
[range={00B1-00B1}]
\definefontfamily[mainface][serif][Tex Gyre Pagella]
\definefontfamily[mainface][math][Tex Gyre Pagella Math]
\starttext
\switchtobodyfont[pagella] Hello $ x \pm 2 = a \mp 2 $\par
\switchtobodyfont[asana] Hello $ x \pm 2 = a \mp 2 $\par
\switchtobodyfont[mainface] Hello $ x \pm 2 = a \mp 2 $\par
\stoptext
% Stop example
The sample with
\switchtobodyfont[asana] Hello $ x \pm 2 = a \mp 2 $\par
looks quite fine.
Best regards: OK
