Not rounding numbers in excel

Помогла ли Вам статья?

Hello, welcome to another #formulafriday blog post for some more formula fun on a Friday – why not?. Today let’s take a look and explore the issue of Excel rounding or not rounding numbers. You may have come across this in Excel especially when working with currency values. Rounding your values may work in some scenarios, but you may NOT want to round up figures in some circumstances. Take a look at an example, you may have a yearly charge of a service, which is split between 12 monthly payments. See my screenshot below.

Excel Rounding- Do You Want It?

The example above Excel has rounded the monthly charge to 10. This is not pricing that the sales department want to promote the service at in their online advertisement. Excel will automatically round the numbers if the column is not wide enough to display the entire number, or when it’s format is set to show a smaller number of decimal places than the original number contains.

If you enter a number into a worksheet cell that has General formatting, like all cells in a new worksheet, the number will be rounded so it fits into the cell. In the case of our promotion of monthly service the display in the cell is 10 but in the formula bar, you can see that the actual entire number is still available in full.

To toggle between seeing the formula and the result of the formula in the formula bar you can click into the formula bar then hit the F9 button. Hit the ESC key to return to the display to the formula again.

Using The TRUNC Function.

The TRUNC function returns a truncated number based on a given number of digits. The Syntax of TRUNC is

=TRUNC (number, [num_digits]) where

number = the number to truncate

num_digits = an optional argument with which to determine the precision of the truncation. The default is 0.

TRUNC removes the fractional part of the number and returns just the integer. For example,

4.9 would return 4

5.25 would return 5

As you can see this is a lot different to the automatically rounded numbers that Excel usually displays. So, if you want only the integer part of your number use TRUNC. Back to our online sales example. The sales department do want to use the monthly payments of 10.00 that Excel rounds to automatically instead we have to force the 9.99 offer they want to market to their online customers. Ok, so that is no problem for us now. As well as just returning integers TRUNC can also be used with the optional argument num_digits. This will return a specified number of decimal places, again with no rounding.

The Solution!

So we can use the TRUNC formula for our problem as we can specify that it uses 2 as the optional argument as the number of digits.

Our formula would look like this

Solved!. We can keep the sales department happy.

Do You Need Help With An Excel Problem?.

I am pleased to announce I have teamed up with Excel Rescue, where you can get help with Excel FAST.

Microsoft has designed excel in a way that will be efficient and easy to use for its users. However, some of the features of Excel can be counterproductive and thus reducing its efficiency. Rounding off large numbers is one of these features that are times counterproductive. When dealing with large numbers on excel cells, excel decides to round off the number hence not displaying the exact number inputted. This may be brought about by issues like; the number inputted is too large to be accommodated by the cell’s width and the cell formatted nature of rounding off large numbers.

To stop excel from rounding off numbers is possible and can be achieved by altering the cell’s settings. Let us now discuss the procedure to be followed in doing this.

1. Open the excel

Double click the Excel app icon, which resembles a green with a white «X» on it. And then, open either a new document or an existing document on your device that you want to change the cell setting.

2. Input your large numbers

On the blank screen of excel, choose and select any blank cell to input the number. Within the cell, input the number of any length and click anywhere outside the cell to save the cell’s data. As expected, Excel will automatically convert the large number into a smaller rounded-off number. Now it’s upon the user to alter the settings to regain the original large number.

3. Click the cell

Click the cell that contains the rounded-off number. Then, right-click to access the cell’s side setting.

4. Click the Format cells button

On the side setting, locate and click on the format cells button. This is where the entire cell’s setting and other cell features are contained.

5. Tap the number tab

On the format cells screen, locate and tap the number bar on the top leftmost most of the screen. And then, select the number button on the left side of the page.

6. Change the decimal places figures

If you’re working with data that contains decimal places, click the up or down button next to «Decimal places» and then adjust/increase the decimal place figures according to your data. Then, click «OK» to save changes. Otherwise, if you’re working with large whole numbers, you can alter the cell settings by only clicking the «OK» button without altering with any other setting on this screen.

Your data on the selected cell will be converted to its original format by clicking the OK button.

Also, once you’ve changed the data on that cell, all the cells found in the same column will be formatted. Thus, you can enter large numbers on that column without having to change the cell setting. This makes it easier and more efficient for the user to input large numbers on the same column.
