Hello, I was surprised by how 10 minutes was converted to 0.02 hour in a table:
| Tâche | HH:MM | Frac | |------------+-------+------| | Avril 2011 | 0:1O | 0.02 | |------------+-------+------| | | | 0.02 | #+TBLFM: $3='(/ (float (org-hh:mm-string-to-minutes $2)) 60.);%.2f::@3$3=vsum(@-I..@-II) I took me less than 2 minutes to discover the problem -- wanna play the "1 diff game" (in the table itself, not in the formula)? -- and fix it: | Tâche | HH:MM | Frac | |------------+-------+------| | Avril 2011 | 0:10 | 0.17 | |------------+-------+------| | | | 0.17 | #+TBLFM: $3='(/ (float (org-hh:mm-string-to-minutes $2)) 60.);%.2f::@3$3=vsum(@-I..@-II) But I'm surprised I did not see any error reported.
