Re: [Orgmode] decimal fractions when summing up large numbers

[Carsten Dominik]

Hi Rainer,

turns out, org-table-sum is an old function I have not looked at for a  
long time.  It used (format "%g" res) to format the final result for  
display - bad idea indeed, because that causes the unwanted rounding.

I have removed this, the change has just been pushed to the git repo.

Thanks for the report.
