Getting Rid of Negative Zero Amounts

When you are creating a worksheet, and you format your cells to display information just the way you want, you may notice that you end up with "negative zero" amounts. Everyone learned in math classes that zero is not a negative number. So why does Excel show some zero amounts as negative?

The reason is because your formatting may call for displaying less information than Excel uses internally for its calculations. For instance, Excel keeps track of numbers out to fifteen decimal places. If your display only shows two decimal places, it is possible that a calculated value could be very small, and when rounded show as zero. If the calculated value is something like –0.000001325, then the value would show with only two digits to the right of the decimal point as –0.00. The negative sign shows, of course, because the internal value maintained by Excel is below zero.

There are a couple of ways you can solve this problem. The first is to simply round the calculated value to the desired number of decimal places. For instance, assume that this is your normal formula—the one that results in the "negative zero" values:

=SUM(A3:A23)

You can round the value in the cell by simply using the following formula instead:

=ROUND(SUM(A3:A23),2)

This usage results in the value being rounded to two decimal places. In this way you should never end up with another "negative zero" value.

Another solution preferred by some people is to force Excel to use the same internal precision as what you have displayed in your worksheet. Just follow these steps:

  1. Choose Options from the Tools menu. Excel displays the Options dialog box.
  2. Make sure the Calculation tab is selected. (See Figure 1.)
  3. Figure 1. The Calculation tab of the Options dialog box.

  4. Ensure that the Precision As Displayed check box is selected.
  5. Click on OK.

What is three minus 1?

Nope. That's not it...in my case.
Simple spreadsheet, with a repeating formula down the lines - subtraction one neighboring cell from another. (ie., G6-H6, G7-H7, etc.)
In many cases the answer is zero. Yet, some of those zeros are in negative form.
It doesn't matter how you format the cell to display (minus sign, in red, red in parentheses).
Convert to $... they'll display as negative zero dollars.
Perform the identical function in some random cell; same neg. result.

"G6" is the product of simple subtraction. "H6" is a hand-entered, 2 decimal place number.
Here's an exact example of "G6" - always derived from 2 hand-entered, 2 decimal place, numbers: 2424.02 - 2351.28. G6 populates 72.74.
The next formula involves subtracting a hand entered 72.74 from G6 (72.74) . Results? Negative 0.

Funny. If I conduct the exact same on a different spreadsheet, my answer is not zero, but -2.13E -13. with format at default General.
And, in Number that is what I see when I go out to 26 places; 0.00000000000000213162.......
Except for the fact that it displays as neg 0 when out less decimal places,

I'm clearly confused. I'm not dividing by some prime number; just subtracting one hand-entered, 2 decimal place number from another number derived from simple subtraction.
