Hello,


I am trying to understand why the floatp lisp function does not seem to
detect exponential scientific notation in babel octave mode.


If I do


#+BEGIN_SRC emacs-lisp

(floatp 1e4)

#+END_SRC


#+RESULTS:

: t


whereas in the following table is converted into char due to the presence
of the third column.


#+RESULTS: variables

| 1 | 1 | 1e-05 |


#+HEADERS: :var a=3Dvariables

#+BEGIN_SRC octave :results output replace

whos a

#+END_SRC


#+RESULTS:

: Variables in the current scope:

: Attr Name Size Bytes Class
: =3D=3D=3D=3D =3D=3D=3D=3D =3D=3D=3D=3D =3D=3D=3D=3D=3D =3D=3D=3D=3D=3D
: a 1x7 7 char

:


Can we modify something so that exponential notation is supported?
