org-table with different conventions: decimals

[Uwe Brauer]

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
