On the File menu, click Preferences.
On the General tab, in the Numeric field accuracy list, select the required percentage accuracy for displaying data.
Click OK or another tab.
Although the accuracy that you choose influences the number of decimal places displayed, this influence varies with the order of magnitude of the value. For example, if you select 10% accuracy, a value of 0.456789 is displayed as 0.46, and a value of 456.789 is displayed as 457. If you select 0.1% accuracy, the first value is displayed as 0.4568 and the second value as 456.8.
