Created attachment 160127 [details] Calc document containing highlighted calculation errors Attached document contains several formulas where the sum of some results with one EURO cent missing. I've marked them red to make it clear. I could not detect any rounding or foramtting issues. The errors survived several document changes to remove personal data. To examine simply - download attached file - open with LibreOffice calc - evaluate the results
Following this thread in de-discuss mailinglist [1] it is a rounding issue which I did not detect due to missing knowledge about foramatting. [1] https://listarchives.libreoffice.org/de/discuss/msg23612.html so all well ;o))
Quickfix to get rid of this, set: Tools -> options -> LibreOffice Calc -> Calculate -> [x] Precision as shown You probably face performance issues with this setting.
