Hi Wolfang,
Thank you for your reply. I have indeed not explained my intended result very clearly.
1.
Primarily, I need to get the two values aligned at the digit separator of the first and second number respectively and overall at the ± sign. I’m working in an xtable, where I have entries such as
\startxcell \mpm{14.0==}{_1.5==} \stopxcell
\startxcell \mpm{_0.034}{_0.013} \stopxcell
and defined
\def\mpm#1#2{
\ifsecondargument
\digits{#1}\,±\,\digits{#2}%
\else
\digits{#1}%
\fi
}
Since I was hoping that I could exploit the zeropadding of \digits to get the format right. Indeed, it would save a lot of typing, if I wouldn’t have to specify the padding manually and I vaguely recall that there is somewhere a ConTeXt solution that can make such alignments, but I simply can’t find it any more …
2. + 3.
Absolutely right, this is my bad. I have badly mixed from Hans’ solution to a similar problem,
https://www.mail-archive.com/ntg-context@ntg.nl/msg00724.html
which was actually \def\zeroamount{-} and the example in the source, I didn’t read properly. Just skip that part. :)
4.
Indeed,
\startxcell \mpm{14.==}{_1.5=} \stopxcell
\startxcell \mpm{_0.03}{_0.01} \stopxcell
aligns properly. But sometimes, I have the first digit specified, but not the second and unfortunately this doesn’t work
\startxcell \mpm{14.5=}{_1.5=} \stopxcell
\startxcell \mpm{_0.03}{_0.01} \stopxcell
because = is not immediately preceded by .
