Re: [NTG-context] mkiv digits/units zero padding not working
Following up on the work-around, here is my improved code for xtable.
What doesn’t work is:
* alignment on the decimal separator takes place only in the first column with
decimals (i.e. B), not on the following one; this is independent of R1 having
a decimal value in this column or not
* row spanning is now tricky since the width of the header column is taken for
the first of the three rows spanned, which becomes even more complicated with
option=stretch, I guess if I right align the second column and would phantomize
the hsize of the header, this could work with a bit of optimization.
What I like about this approach however is that one could read the two
arguments from a CSV file, which would save a lot of typing (and to manually
specify the padding).
\def\mpm#1#2{
\doifsomethingelse{#2}{
\startxcell[align=left] \digits{#1} \stopxcell
\startxcell ± \stopxcell
\startxcell \digits{#2} \stopxcell
}{
\startxcell[align=left] \digits{#1} \stopxcell
\startxcell \stopxcell
\startxcell \digits{#2} \stopxcell
}
}
\startxtable[split=repeat, aligncharacter=yes, alignmentcharacter={.}]
\startxtablehead
\startxrow[topframe=on, foregroundstyle=bold]

Re: [NTG-context] mkiv digits/units zero padding not working
Hi Wolfgang,
you are (of course) right again. I realised that I wouldn’t get the expected
behaviour after checking the snippet isolated from my document’s context, where
it is embedded in a \startplacetable[…]{}{}. I’m still learning to get the gist
of the \doifs, the curly and square bracketed arguments and so on. Thanks for
the hint!
Seems like I’m going to make three cells and span the header column for now,
though I guess it would be a nice feature to have the padding working in the
other cases.
I’ll write a feature request for no 4.
Thanks!

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
}
Is there something missing in here because the \ifsecondargument check
here makes non sense because the second argument is mandatory and not
optional.
Is this what you want?
\define[2]\mpm
{\digits{#1}%
\doifsomething{#2}{\,±\,\digits{#2}}}
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

You can align number on the decimal point (comma) but this works only
when you have only one number in a cell.
\starttext
\startxtable[aligncharacter=yes,alignmentcharacter=±]
\startxrow
\startxcell
\digits {14.0} ± \digits {1.5}
\stopxcell
\stopxrow

\startxcell
\digits {0.034} ± \digits {0.013}
\stopxcell

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

The message is from 2003!
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 .
Can you write another mail with a request for this.

Hi,
I’m trying to get

\digits{_8.12}±\digits{0.34}
horizontally aligned as
15.0 ±1.00

But I get
15.0±1.00
8.12±0.34

From the source (phys-dim.mkiv), I can see that “=“ should expand to
\hphantom{0}. (I think \zeropoint in the table is outdated, since
\def\zeropoint\hphantom{0} does not solve the problem either.)
1. Which table?
2. This is not how \def works.
3. When you redefine \zeropoint (which isn't a macro) you're going to
break everything.
I can’t use tabulate or alignment in math mode for this problem unfortunately.
I looked at the code and the problem is = can only be used to insert
space for two digits (e.g. 100.==).
