Default Excel Addition Error

Yikes! My bad. I went back to the original data to confirm my statement
that nothing had ever been anything but an integer, and I was WRONG. The
actual original inputs we

442527.6
1477789.2
17942.4
130713.6
84052.8
524606.4
1724961.6
93585.6

Hence, my premise was wrong. I apologise to the community for my error.

Open an Excel spreadsheet, format a column as numeric, no decimals, and paste
in the following 8 values:

442,528
1,477,789
17,942
130,714
84,053
524,606
1,724,962
93,586

Sum them. You will get the answer 4,496,179. The correct answer is
4,496,180. I would suggest you incorporate round-off error correction
routines in your math calculations. This is strictly a newbie error, and I'm
frankly amazed that you haven't caught it yet.
