Hi Carsten et al

Anyone have a clue what is going on here?

Cheers

Will

* Arctan2 bug
Activate the formula editor for the following table with =C-c '=, then
exit without changing anything. Note what happens to the arctan2
formula. For me, "arctan2" changes to "@2$20173232".
| x | y | arctan | arctan2 |
|---+---+--------+---------|
| 1 | 1 |     45 |     45. |
#+TBLFM: $3=arctan($1/$2)::$4=arctan2($1,$2)

** Versions
Org 6.34trans, Aquamacs 2.0preview4, Emacs 23.1.92.1

Org does read arctan2 as a field reference like B4 or AB2 and  
determinates that this is a row REALLY far to the right.

I have fixed this special case.  Are there more functions in calc  
which have names like this?

Thanks for the report!

I confirm that your fix works. Thanks for doing this so fast!

A quick search for digits in the "(calc) Function Index" info node
gives the following list:

arctan2, exp10, expm1, lnp1, log10, stir1, stir2

Here is a list of all the calc operators that I could find, some of
which might confuse your regexps:

!, !!, !!!, !=, %, &&, &&&, *, +, +/-, -, /, :, ::, :=, <, <=, =, ==,
=>, >, >=, ?, \, ^, _, |, ||, |||

I don't think it is necessary to allow all of these in table formulae
since many have synonyms. E.g., `x &&& y' can be written `pand(x, y)'

Cheers

Will

Thanks!  I am catching aything now that has more than two letters,  
which is probably OK (it assumes that org tables will never have more  
than 676 rows....).

I think these are all OK.  Only problem *might* be && and &&&, but
I think we should be fine here as well.

Thanks for your very complete answer!
