Re^2: accurately rounding numbers for percentages
in thread accurately rounding numbers for percentages
That's not what Trimbach said, by a long shot.
If you add the UNrounded
numbers percentages, they should total 100% (except for the fact that you'll sometimes run into value/count pairs that are rounded at the end of whatever length decimal value you use: 100/6, for example).
But, for cases such as I infer yours is, a quite standard and commonly accepted practice is to include the disclaimer "Totals may not equal 100% because of rounding."
Update: For clarity (in light of OP's next reply), s/numbers/percentages/ at strikeout above.
