Hi!
I'm a relatively new emacs and org-mode user so I apologize for the
basic nature of this question. Unfortunately, the answer is probably so
obvious that no one has had to ask it before, and, as a result, I have
not been able to find this subject in the mailing list. Of course, I
may not be doing a good search, so please accept another apology.
Anyway, all I am trying to do is to sum a column of numbers in a table
in an org file. Here's an example:
935.15
6483.80
7419.00
#+TBLFM: @16$4=vsum(@3$4..@4$4);%.2f
The answer is obviously being rounded but I don't want that and I
cannot figure out the undoubtedly trivial way to stop it so I get the
answer that I want to see - 7418.95.
Thanks for any help anyone offers on this simple (but frustrating for
me) question.

Org-mode uses a relatively compact output format for calc in order
to avoid that fields get too wide. You can fix this by changing
the default format in `org-calc-default-mode' from (float 5) to (float
8)
or so, but that means each time a number is produced with many digits,
all 8 will be displayed.
The other option is to change the format on the fly, just for a specific
formula, using (again for example) an f8 flag, like
$4 = vsum($1..$3);f8
Hope this helps.

Carsten,
Many Thanks for your rapid response - your suggestion worked and your
caution was helpful as well (e.g., using f7 showed 3 additional zeros).
For anyone reading the list that might be interested, here's how I
fixed the example to get the two digits to the right of the decimal to
print correctly.
Original table and formula
935.15
6483.80
7419.00
#+TBLFM: @16$4=vsum(@3$4..@4$4);%.2f Original formula yields 7419.00
Fixed table and formula
935.15
6483.80
7419.00
#+TBLFM: @16$4=vsum(@3$4..@4$4);f6%.2f Revised formula yields 7418.95
^^
added formatting
Jim
