How to Stop Excel for Mac from Rounding Values When Reducing Decimals
Question details
The user needs to prevent Excel for Mac from permanently altering and rounding underlying stored values when adjusting the number of displayed decimal places.

- Product
- Excel for Mac
- Device & OS
- Mac
- Scenario
- Adjusting the decimal display format of numeric data in an Excel spreadsheet.
- Observed behavior
- Instead of just changing the visual display, Excel is permanently rounding the actual stored values (e.g., changing 3.5 to 4).
Check if you have a backup of your current spreadsheet, because any data that has already been permanently rounded by this setting cannot be automatically restored.
Disable the Precision as Displayed Setting
Turning off this calculation preference ensures Excel only alters the visual format without modifying the original precise data.
The 'Precision as displayed' feature forces Excel to permanently change stored values to match whatever appears on your screen. Disabling this is the only way to retain exact numeric values while displaying fewer decimal places.
Open Microsoft Excel on your Mac. Navigate to the top menu bar, click on 'Excel', and choose 'Preferences' from the dropdown.
In the Preferences window, locate the 'Formulas and Lists' section and click on the 'Calculation' icon.
Look for the option labeled 'Precision as displayed'. Uncheck the box next to it to turn off the feature, then close the settings window.

Frequently Asked Questions
Why does Excel permanently alter my data when I decrease decimals?
By default, decreasing decimals only changes the visual format. However, if a setting called 'Precision as displayed' is enabled in your Excel Calculation preferences, the software forcibly changes the underlying saved values to perfectly match what is visible on the screen.
Can I undo the 'Precision as displayed' rounding effect on Mac?
No. Once 'Precision as displayed' is applied and the spreadsheet calculates, the original precise decimals are permanently erased from the document's memory. You must re-enter the data manually or restore from a previous file backup.
How do I safely change the number of decimal places?
First, ensure 'Precision as displayed' is completely unchecked in your Calculation settings. Once disabled, you can safely use the 'Increase Decimal' or 'Decrease Decimal' buttons on the Home ribbon to adjust appearances without altering the actual data.
