Hello everyone,
I want to use an org-spreadsheet to perform unit conversions for me.
| Mass (g) | Mass (lb) |
|----------+---------------|
| 300 g | 0.66138679 lb |
| 23 kg | 50.706320 lb |
| 50 Mg | 110231.13 lb |
#+TBLFM: $2=uconvert($1, lb)
I made the table above, but can't figure out how to format the output. I
tried using the ;%.2f notation shown in the manual, but it cuts the
units off for some reason.
Here is what org-table displays with ;%.2f appended onto my table
formula:
| Mass (g) | Mass (lb) |
|----------+---------------|
| 300 g | 0.66 |
| 23 kg | 50.71 |
| 50 Mg | 110231.13 |
#+TBLFM: $2=uconvert($1, lb);%.2f
Here is what I wish appending ;%.2f would cause org-table to display:
| Mass (g) | Mass (lb) |
|----------+---------------|
| 300 g | 0.66 lb |
| 23 kg | 50.71 lb |
| 50 Mg | 110231.13 lb |
#+TBLFM: $2=uconvert($1, lb);%.2f
If you type in '0.66138679 lb into calc directly, and press d f 2, calc
displays 0.66 lb as desired. Is there any reason for the %.2f notation
chops off the units? Is there some better way to accomplish what I
want?
Thanks!
Note: my spreadsheet uses the wrapper function below to convert units with calc.
#+begin_src emacs-lisp
(defmath uconvert (expression new-units)
(math-convert-units expression new-units)))
#+end_src

There might be a better, more local, way of doing it, so take the following as an
existence proof: if you customize the variable org-calc-default-modes and change
the calc-float-format to (fix 2), the table will recalculate to your expectations.
I don't know how to stitch together the better solution however, so I leave that
as an exercise for you :-)

Org spreadsheet gives access to the format of calc, use
#+TBLFM: $2=uconvert($1, lb);f-2
or less recommended the format of Org spreadsheet with a text
#+TBLFM: $2=uconvert($1, lb);%.2f lb

Calc `defmath' is not mentioned in the Org manual or on Worg, so I
suggest the attached patch for the Org manual.
