[Orgmode] Re: org-babel: feature-request: allow table-cells to be passed as strings

[Marc-Oliver Ihm]

Hello,

This would be such an example. The Input table contains some numbers,
the last of them larger than allowed for an integer.

As the result table show, the last one is converted to float thereby
using some precision.

I would like to see them all as strings.

with kind regards, Marc-Oliver Ihm


#+tblname: numbers

|                           1 |
|                           2 |
|                          12 |
|                          45 |
|                         166 |
|                    12567890 |
| 231231282371983279389999999 |


#+begin_src emacs-lisp :var numbers=numbers
(mapcar
 (lambda (line)
     (let ((number (car line)))
       (list number (type-of number))
       )
     )
   numbers)
#+end_src

#+results:
|                      1 | integer |
|                      2 | integer |

|                     45 | integer |
|                    166 | integer |
|               12567890 | integer |
