Hi Seb(astien),
it seems that you're working with calc source blocks! :-) I'd like to
leverage calc in org-mode (I'm thinking of unit conversions, etc.:
Mathematica for free men) but I'm not getting it. I assume that in an
#+src_calc block the mode of operation of calc is algebraic, isn't it?
#+BEGIN_SRC calc
2 + 2
sqrt(8)
# above is working, by the way, does a calc block have a comment sign?
2 cm
calc-convert-units(mm)
#+END_SRC
#+RESULTS:
: calc - convert - units(mm)
Above attempt is not working. Is it also possible to use the RPN? Like
in this fictive block:
#+BEGIN_SRC calc :mode rpn
2 2 +
2 'mm 8 'cm + 'in u c
#+END_SRC
And the *Calc Trail* buffer seems not to reflect any operations, despite
Calc showing the block results in its calculator buffer!
Thanks
Dieter
