Hi,
I’m trying to get
\digits{15.0=}±\digits{1.00}
\digits{_8.12}±\digits{0.34}
horizontally aligned as
15.0 ±1.00
8.12±0.34
But I get
15.0±1.00
8.12±0.34
instead.
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 (I think \zeropoint in the table is outdated, since \def\zeropoint\hphantom{0} does not solve the problem either.)
I can’t use tabulate or alignment in math mode for this problem unfortunately.
Any hints would be very welcome.
Thanks
Benjamin

I looked at the code and the problem is = can only be used to insert space for two digits (e.g. 100.==).

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 . > On 7 May 2020, at 18:21, Wolfgang Schuster <wolfgang.schuster.lists@gmail.com> wrote: > > Benjamin Buchmuller schrieb am 07.05.2020 um 17:31: >> Hi, >> I’m trying to get >> \digits{15.0=}±\digits{1.00} >> \digits{_8.12}±\digits{0.34} >> horizontally aligned as >> 15.0 ±1.00 >> 8.12±0.34 >> But I get >> 15.0±1.00 >> 8.12±0.34 >> instead. >> From the source (phys-dim.mkiv), I can see that “=“ should expand to \hphantom{0}.

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.

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] \startxcell A \stopxcell \startxcell[align=left, nx=3] Bla bla bla bla bla bla bla bla \stopxcell \startxcell C \stopxcell \stopxrow \stopxtablehead \startxtablebody \startxrow[topframe=on] \startxcell R1 \stopxcell \mpm{12.3}{}%{1.5} \startxcell one \stopxcell \stopxrow \startxrow \startxcell R2 \stopxcell \mpm{0.01}{0.023} \startxcell two \stopxcell \stopxrow \startxrow \startxcell R3 \stopxcell \mpm{2.3}{0.1} \startxcell three\stopxcell \stopxrow \stopxtablebody \stopxtable > On 7 May 2020, at 21:22, Benjamin Buchmuller <benjamin.buchmuller@gmail.com> wrote: > > Hi Wolfgang, > > you are (of course) right again.
