# How to Get Excel to Stop Rounding Your Numbers

Isn’t it annoying when Excel just keeps rounding off numbers?  Below table shows some common examples:

Figure 1. Examples of Excel Rounding Off Numbers

There are several possible reasons but the most common are these:

• Column width too narrow and doesn’t display the whole number
• The number of decimal places is set to fewer digits than the actual decimal places
• The number is too large and exceeds 15 digits; Excel is limited to display only 15 significant digits
• The default format for every cell in Excel is set to “General” and not “Number”

• Stop Excel From Rounding Whole Numbers
• Stop Excel From Rounding Currency

## Stop Excel From Rounding Large Numbers

There are instances when we need to enter large numbers, such as credit card or reference numbers. Unfortunately, Excel has a limitation and displays only 15 significant digits. The excess digits will be changed to zeros.

Example: In cell D3, enter the number “346003617942512178”, which contains 18 digits.

Press enter.  Cell D2 will display the value “3.46004E+17” while the formula bar will display the value “346003617942512000”.

Notes:

• The 16th to 18th digits are changed from “178” to “000”.
• The displayed value only shows 6 significant digits because default format in Excel is “General”
• To display the 18-digit number 346003617942512000, select D3 and press Ctrl + 1 to launch the Format Cells dialog box.  Select the format “Number” and set the decimal places to zero “0”.  The 18-digit number is now displayed in D3.

But how to display the original number 346003617942512178?

Work-around:

To stop Excel from rounding a large number, especially those exceeding 15 digits, we can:

• Format the cell as text before entering the number; or
• Enter the number as a text by entering an apostrophe “ before the number
• Example: Enter into cell D3: ‘346003617942512178

## Stop Excel From Rounding Whole Numbers

Let’s take for example the value of pi(), which is commonly used in mathematical equations.

Example 1 : In cell D3, enter the formula =pi(). Column E displays the value of pi with varying number of decimal places.

Work-around:

To stop Excel from rounding whole numbers, click the Increase Decimal button in the Home > Number tab.  Increase the decimal place until the desired number of decimal places is displayed.

Example 2: In cell D3, enter the number 123456789, and see how Excel rounds off the number into varying number of significant digits, depending on the column width.

Work-around:

To stop Excel from rounding a whole number, we can adjust the column width to display all the digits.

## Stop Excel From Rounding Currency

Most currencies have two decimal places. Rounding currencies might have a small impact since it will only be dealing with tenths or hundredths of a currency, such as centavos.

There are instances, however, where rounding currencies becomes serious. In Accounting, for example, in order to arrive at a more accurate result, rounding should be done only as needed, or as late into the calculations as possible.

The table above shows the effect of rounding currencies into the total commission.

Work-around:

To stop Excel from rounding currencies, format the decimal places to “3 or more”.  This way, the precision and accuracy of our data is preserved as close to the original value as possible.
