How to count (identify) and change decimal place in Excel?

This article will show you the way to count and identify the decimal place of a number, and ways to change decimal place in a given range or the whole worksheet.

Supposing we will count and change the decimal places of numbers in the given Column A, see the following screenshot:

Sometimes there are numbers containing various amount of decimal place, and you may want to count the digitals and show in a cell. You can do it with following steps:

In a blank cell, saying the Cell B2, enter the formula of =IF(A2=INT(A2),0,LEN(MID(A2-INT(A2),FIND(".",A2,1),LEN(A2)-FIND(".",A2,1)))), and press the Enter key.doc-count-change-decimal-places2

Then it returns the decimal place in the Cell B2. In this case, it shows 5. Now you can get the decimal place of other numbers with copying and pasting this formula to corresponding cells.

You can change the decimal place for many numbers in a given range with following steps:

Step 1: Select the numbers you will change their decimal place. In this case, select the range of A2:A6.

Step 2: Click the Decrease Decimal button or Increase Decimal button in the Number group under Home tab.

Step 3: Then the decimal place of numbers in the selection are changed and unified to same decimal place. See the following screenshot:


You can also change and unify the decimal place of numbers with Format Cells by right clicking the selection.

Step 1: Select the range that you want to change, and right click.

Step 2: Choose Format Cells from the context menu, and in the Format Cells dialog box, click Number from the Category list, and enter the decimal places that you need. See screenshot:


Step 3: Then click OK. And the decimal places have been changed to what you want.

This method will help you change the default decimal place for the whole worksheet.

Step 1: Click the File > Options in Excel 2010; and click the Office Button > Excel Options in Excel 2007;

Step 2: In the Excel Options dialog box, click the Advanced button in left bar.

Step 3: Go to the Editing options section.

Step 4: Check the Automatically insert a decimal point option, and enter a number in the Places box.

Step 5: Click OK to confirm and save the changes. Now the default decimal place is changed.

Step 6: When you input the number 1234, it will become 12.34 automatically, if the default decimal place is 2.


By the way, if you enter the number of 16.25893, it will shows as 16.25893, but not 16.26.

Kindly tell me if it is possible to add values with their decimal values separately ie 47.6+49.5=96.11. Does excel have a formula to deal with this one. If anybody knows, It would help me so much. Thanks. Robbie

The formula for counting the number of decimal places is flawed. For example, 123.75 returns 1.

this formula works.. please try this.. =LEN(MID(A1,1+FIND(".",A1),99))

How can you change the decimal place for values that are already in the cell? In other words, i'm not trying to change the number of decimal place showing, but want to convert the value of the number in the cell. To illustrate: Change 1.25 (cell a) to 125 (cell b). Is this possible without having to go through each cell to convert? Thanks!

Run an equation in the adjacent column =A1*100, clicking bottom right corner of the box/dragging, to run down the length of the column.

This only works for two digit numbers, middle of the mid function should always be 3 since when you take the decimal part the numbers will always start in the third place. Lame that I have to correct this.

I have a cell that already contains a long formula, but can generate results from 0.01 up to 10000.Ideally would like a way of formatting the cell such that it automatically adjusts the decimal point based upon the results.e.g.numbers < 100 would have 2 d.p.numbers <1000 would have 1 d.p.numbers >=1000 would have 0 d.p.
Can see how to achieve this using rounding function with multiple IF commands, however with the length of formula this is unmanagable:e.g.=ROUND("FORMULA",(IF("FORMULA">=1000,0,(IF("FORMULA">=100,1,2)))))
Is there a tool or function within Excel that can achieve this?If not is there a way of doing this without having to repeat the formula in the IF functions?
Ideally don't want to put VBA into the workbook or spread the calculation across multiple cells.
