Hi
In my current setting, the following works
| 3.5 | 4.2 | 7.7 |
#+TBLFM: $3=$1+$2
Now if I want to switch to the convention used in Germany (that might be
relevant if I want to export it later to csv, but this is a different
topic) does work in a strange way, any comments? I would expect
| 3,5 | 4,2 | (7, 7) |
#+TBLFM: $3=$1+$2
| 3,5 | 4,2 | 7,7 |
#+TBLFM: $3=$1+$2

Hi, Uwe,
If you only need to export to LaTeX you can load the siunitx package,
which not only fits the decimals perfectly in a table but you can also
define a value for the decimal sign that will be seen in the PDF.
It has a small drawback. Columns with numeric value (S) cannot contain
anything other than numbers. If you want to add an arbitrary text string
in one of those columns you must enclose that string in {}. That is, on
the org side it would be @@latex:{foo}@@
You can try this with your example:
#+LaTeX_Header: \usepackage{siunitx}
#+LaTeX_Header: \sisetup{detect-all}
#+LaTeX_Header: \sisetup{output-decimal-marker = {,}}
#+ATTR_LaTeX: :align SSS
| 3.5 | 4.2 | 7.7 |
#+TBLFM: $3=$1+$2
Best regards,
Juan Manuel

Thanks but I don't want to export the table to latex, instead I want to
export it to CSV and later import it into Scalc (LO).
So I think the correct way of dealing with this situation is not export
it with english convention to csv and then in Scalc set the default
language to German and import the csv as English (US).
That is a bit cumbersome, but doable.
Regards (take care with the heat if you live in Spain (not sure though))

Org tables use Emacs' calc under the hood by default.
AFAIK, calc is unable to use "," as decimal point because it is reserved
as a vector separator. Which is why you got the vector addition in your
example.

Thanks. I was afraid that the issue was with calc not with org-mode.

Note that you can instead use Elisp formulas. See 3.5.3 Emacs Lisp forms
as formulas. It is more flexible.
Alternatively, we may implement the comma separators as a built-in
feature. Org table formulas already support notations like
| 3,5 | 4,2 | 7 |
#+TBLFM: $3=$1+$2;N
or
#+TBLFM: $3=$1+$2;E
#+TBLFM: $3=$1+$2;L
(see 3.5.2 Formula syntax for Calc)
we may as well implement something like ";Nc" that will interpret cells
as numbers with "," as decimal point separator.
Is there such a demand?
Best,
Ihor

Can you give me an example?

Not sure I understand this
| 3,5 | 4,2 | 7 | (7, 7) | (7, 7) |
| | | | | |
#+TBLFM: $3=$1+$2;N::$4=$1+$2;E::$5=$1+$2;L

I think others should speak up, all I can say
1. «,» is the standard in German speaking countries, while
2. «'» is the standard in Spanish speaking countries
For the separator.
In my use case I need to generate ods documents that use the
German language setting, org-mode however relying on calc needs the
notation that the «.» Separate digits while in German it is the «,».
I solve this issue by exporting my org-table to csv, set scalc to German
as a default language, and then import the csv file, using American
English.

Yes, it is awkward. Yet possible.

;N means "convert to number using string-to-number".
(string-to-number "3,5") ;; => 3
why? read the docstring (it ignores non-recognized trailing chars ",5")
L makes no sense in calc formulas (it has no effect).
E refers to dealing with empty field and has no effect here.
Best,
Ihor

That's interesting.
I remember an earlier discussion that settled on the recommendation to
keep the spreadsheet as it is and use export-hooks if one needs to
change the decimal separator upon export. My contribution to the
discussion also gave Carsten the idea of starting a Worg page called
org-madness.org. :-).
Thread started here:
https://lists.gnu.org/archive/html/emacs-orgmode/2011-05/msg00551.html
But I don't think we considered the possibility of a flag to make Org
translate dot-separated decimals into comma-separated ones for
Calc. That could offer more fine-grained control than export processing
when you need some dots to stay dots. And it would certainly be less
challenging for users who just want things to work without digging into
advanced export options!
Export processing (which has since become more fine-grained with the
introduction of filters) remains an option, though, and some backends
offer further possibilities.
Yours,
Christian
