Sherry has a column of numbers ranging from 13 to 15 digits long. She needs to remove just the last digit in each number and wonders how this can be easily done.

The easiest way is to use a formula to strip off the digit. The following works just fine, assuming that the original value is in cell A1:

=LEFT(A1,LEN(A1)-1)*1

What is returned by the LEFT function is a string, which is why it is multiplied by 1 at the end of the formula—it converts that string value back into a numeric value.

Perhaps the shortest formula would be the following, however:

=TRUNC(A1/10)

Dividing by 10, of course, is a quick way to move the decimal point one position to the left. You could use the INT function instead of TRUNC, but you should only do so if the original values are all positive numbers. (INT and TRUNC behave differently from each other when working with negative values.)

Obviously, the formulas described above require the use of a helper column. They also aren't terribly discriminating; they will remove the last digit from any value in cell A1 and they won't "adjust" if A1 contains text or is empty. If you want a bit more flexibility, you might consider using a macro:

Sub ShortenByOne() Dim c As Range For Each c In Selection If (Not c.HasFormula) And (Application.WorksheetFunction.IsNumber(c)) Then c = Left(c, Len(c) - 1) End If Next c End Sub

To use the macro, select the range of cells you want to affect and then run it. The values are changed to reflect the dropping of the right-most digit. Note that the macro won't make any changes in cells containing formulas or cells that don't contain numeric values. (The IsNumber worksheet function is used in preference to the IsNumeric function because IsNumeric will treat empty cells as if they are actually numeric which will crash the macro without additional testing. IsNumber doesn't exhibit that problem.)

If you want to make sure that only cells containing 13, 14, or 15 digits are modified, then you can use a variation on the above macro:

Sub ShortenByOne() Dim c As Range For Each c In Selection If (Not c.HasFormula) And (Application.WorksheetFunction.IsNumber(c)) Then If Len(c) > 12 And Len(c) < 16 Then c = Left(c, Len(c) - 1) End If End If Next c End Sub

Note that after the macro determines that the cell doesn't contain a formula and that it contains a number, then it checks to see if the length of the number is greater than 12 and less than 16. (In other words, 13, 14, or 15.) Only then does it strip off the right-most digit.

since the first properly handles decimals as well as whole numbers in the 13-15digit samples.

Example: 111111111111.1 is properly handled by the LEFT function.

thanks
