Reading through the linked thread it seems to be a result of pre AND post processing of the value before it is rendered. The fact that A1-1 and A1+1 (where A1 is the SUM()) give different results lend some weight to this argument.

some kind of display thing....

I just did 850 * 77 that gave 65,450.000
then the 850 * 77.100 gave 100,000.000
when I did =d8-c8 i got 85.00

but wnen i manualy entered 100,000 and 65,450 and did the subtract i got 34,550.00

so my off the cuff look says that internally the number is right but the display is wrong.

but yes MSFT needs to see this and jump on it.

According to Excel 2007

85000*.771 = 65535
8500*7.71 = 65535
850*77.1 = 100000
85*771 = 65535
8.5*7710 = 65535
(850*7.71)*10 = 65535
850*(7.71*10) = 100000

What I don't get is why it's base 10 "100000". It's clear that the problem is that the floating point multiplication has overflown the two-byte box that the number has, but it's bizarre to say the least that it chose to overflow to 100000. I could even understand it going to 0x100000 (overwrite on the buffer - potential hackable hazard).

Back in yonder days of old, when I was less lazy than I am now, I'd attack Excel with the stick of debug and give you an actual answer, but Excel is big and I am lazy, so I can't be bothered.

At this site an investigator performed a simple loop to calculate (65535/x)*x for x = 1, ..., 65535.  For over 10,000 values of x, it gave 100,000 rather than 65,535 as the answer.

If you have a stock whose value is fluctuating close to 77, keep watching the ticker to see when to sell 850 shares of it!

Sadly progrommatic access through excel shows 65535 when it autocasts to a float, double or int, and most of the big financial companies are more prudent than to upgrade their software if the old one works.

That being said, it's unacceptable since grandpa joe might be paying for a bottom-line that has been incorrectly computed by davy-smith and sons local accountants firm ltd.

1 is between 0.99999999995 and 1
2 is between 1.99999999995 and 2
3 is between 2.99999999995 and 3

I think it means that it is post-processing where they decide how to display the value that is causing the problem, not the calculation of the actual value - I could be (and probably am) wrong.  I don't however think that saying "This'll only happen with a few thousand number" really mitigates the situation.

I'm taking bets on how long before-
1. A lawsuit
2. An update

A2: =A1+1
A3: =A2+1

Result in A3 = 65537

A1: =850*77.1
A2: =ROUND(A1,1)+1
A3: =A2+1

Result in A3 = 100002

Are you sure it's not some puzzling with , (comma) and . (dot)?

Errr.. he has access to the code and debugger. I'm gonna go with his version of events, rather than your "superior knowledge" on the subject.

It's actually provable that it's not just a display bug:
A1: =850*77.1
A2: =ROUND(A1,1)+1
A3: =A2+1

Result in A3 = 100002

Since that only seems to happen when rounding, it suggests there is another subtle bug in ROUND that only surfaces when the displayed value doesn't match the stored value.

Or that the display bug is actually a result of a bug in their rounding routine (as displayed values are always rounded to the 15th decimal place).

Maybe you guys aren't thinking the bug isn't in the calculation as such, its in the cell being able to show the result of the value correctly.. the +1 thing is just +1 to whatever the REAL value of the 100000 cell is..

The whole concept of decimal in binary systems is tainted, its just ~how~ tainted it is..

Still, pretty bad bug to release..

ROUND() is burden by how it's usually used, that is to represent something to the nearest dollars, for example:

A1 = 0.95   B1 = ROUND(A1) = 1
A2 = 0.95   B2 = ROUND(A2) = 1
            B3 = SUM(B1:B2) = 2

In B3, people don't want to see 1.9 -- and even though, you could as easily ROUND(B3)... people want the SUM of B1 : B2 to be the natural SUM of what they see.

So, somehow, ROUND bakes the translated value into the cell... in this case, the value is translated incorrectly.

So, any function that requires baking the translated value into the cell, I think would be subject to this bug.

How embarassing.

Even before the Excel blog was posted, some slashdotters had already demonstrated that this is a display-only bug .  See this slashdot sub-thread:
And yet it works FINE when you GRAPH it...

Most of the time people don't read cells themselves, rather automated processes perform spreadsheet calculations, update database with the results, update spreadsheets, etc.  Humans normally look at prepared graphs, which apparently isn't affected by this problem.  But this is still very bad for cases where human eyes are looking directly at the cells to read data.
