how to avoid 0.0 in an org-table

[Uwe Brauer]

Hi 

In the following example 

#+begin_src elisp
|     |    |   |   |  Res | Min |
|-----+----+---+---+------+-----|
|   0 |  0 | 0 | 0 |    0 | 0.0 |
| 1.2 | 10 | 1 | 1 | 13.2 | 0.1 |
#+TBLFM: $5=vsum($1..$4);f1::$6=min(10,$4)*0.1;f1 E
#+end_src

I obtain 0.0 in the last column, this looks bad, any idea how to avoid
it?

Thanks
