Setting the number of decimal places displayed for measurements

By default, ArcMap displays measurements and other numbers with three decimal places while editing. These measurements include the values reported when you are creating new features, such as the distance between two vertices or the current coordinate location of the pointer, and the values shown on the Edit Sketch Properties window.

Note:

The number formatting settings on the Fields tab of the Layer Properties dialog box are used when displaying numeric values on the Attributes window and the table window.

Steps:

1. Click the Editor menu and click Options.
2. Click the General tab.
3. Type the number of decimal places you want to use.
4. Click OK.
