Fill Series function adding extra decimal data

I needed to fill a column with the numbers 2.30 thru 10.00.  I put in 2.30 and 2.31, and then used the Fill Series function by grapping the black square and dragging it down til I got 10.00.

When I investigate the cells, they have the number expect.

For a while.

Suddenly I start getting extra decimal data.

The first one occurs at 2.54

And it just grows.

As you can see I don't have any added formatting.  It defaults to General.

 

Where is this extra decimal data coming from?

I even tried using a formula where my first cell is 2.3 and my next cell is the previous cell + 0.01.  Fill Series down til 10.00.  I then take those cells and copy the value.  Same extra decimal data.

BUT...

For kicks I tried it with 0, 0.1, and 0.2 and did the Series Fill. That's clean all the way to 10.

  • This is due to the way Excel stores and processes decimal numbers.

    If you have a recent version of Excel:

    =SEQUENCE(771, , 230)/100

    If you have an older version, enter 2.3 in the first cell, say C2.

    In C3, enter =ROUND(C2+0.01, 2)

    Fill down.
