This article was previously published under Q78288 SYMPTOMS
If you are in a spreadsheet working with a pie chart, you may find that
percentages of rounded numbers in the chart add up to more than 100 percent.
For example, the spreadsheet numbers 3, 6, 10, and 12 generate the percentages 9.7, 19.4, 32.3, and 38.7, respectively, in a pie chart. These percentages add up to 100.1 percent.
CAUSE
This can happen whenever numbers are rounded and then summed. If you have
the numbers 7.3, 7.4, and 7.3, the sum is 22. If you round them to integers
and sum them, the result is 21. In the pie chart, the percentages you are
adding are not exact percentages, but percentages rounded to one digit
after the decimal point. The sum of these rounded percentages may be
different (99.9 or 100.1 in the cases described) than the sum of the exact
percentage, which would be 100.
