--- Comment #6 from Michael Warner <michael.warner.ut+libreoff...@gmail.com> --- Maintaining precision to a large number of decimal places is impossible due to the way computers store floating point numbers. Excel has the same issue, see: https://en.wikipedia.org/wiki/Numeric_precision_in_Microsoft_Excel If you don't truly need precision to 20 decimal places, then I recommend you either change the cell formatting to reduce the number displayed, or use ROUND in your calculations. -- You are receiving this mail because: You are the assignee for the bug.
