Hello,
Taking the opposite of a time (that is, "putting" a minus sign in front of it)
changes its value...
Here, a quick ECM to demonstrate the above:
* Grand total
#+TBLNAME: GrandTot
| Total | 232:11 |
* Other total
#+TBLNAME: OtherTot
| Total | 158:07 |
* Computation
** OK
The "other total time" is to be divided by 2, and substracted from the "grand
total time".
| | Time |
|--------------------------+--------|
| Grand total | 232:11 |
| - Other total / 2 | 79:03 |
|--------------------------+--------|
| = Total to be considered | 153:08 |
#+TBLFM: @2$2=remote(GrandTot,@1$2);T::@3$2=remote(OtherTot,@1$2)/2;T::@4$2=@2-@3;T
That's correct.
** Not OK
However, I would like to clearly state that the amounts do no add, by having a
minus sign in the time column:
| | Time |
|--------------------------+--------|
| Grand total | 232:11 |
| - Other total / 2 | -80:56 |
|--------------------------+--------|
| = Total to be considered | 151:15 |
#+TBLFM: @2$2=remote(GrandTot,@1$2);T::@3$2=-remote(OtherTot,@1$2)/2;T::@4$2=@2+@3;T
Whoops! Not the same results...
Other variations also fail:
| | Time |
|--------------------------+--------|
| Grand total | 232:11 |
| - Other total / 2 | -80:56 |
|--------------------------+--------|
| = Total to be considered | 151:15 |
#+TBLFM: @2$2=remote(GrandTot,@1$2);T::@3$2=remote(OtherTot,@1$2)/-2;T::@4$2=@2+@3;T
or
| | Time |
|--------------------------+--------|
| Grand total | 232:11 |
| - Other total / 2 | -80:56 |
|--------------------------+--------|
| = Total to be considered | 151:15 |
#+TBLFM: @2$2=remote(GrandTot,@1$2);T::@3$2=remote(OtherTot,@1$2)/2*-1;T::@4$2=@2+@3;T
Best regards,
Seb

Fixed... please confirm.
Thanks *a lot* for reporting this -- this was indeed a nasty bug.

This is the least I could do... Thanks for your help.
