Specify decimal places in attribute tables and labels in ArcGIS Pro

Summary

When adding raw data containing numbers to ArcGIS Pro, significant figures are preserved to ensure precision when performing data analysis. To present the result, the numbers are rounded to a given number of decimal places. This article describes the workflows to round numbers in an attribute table and label in ArcGIS Pro.

Procedure

Round numbers in the attribute table

1. Open the ArcGIS Pro project.
2. Open the attribute table.
3. In the attribute table, right-click the numeric field, and click Fields.
4. In the Fields view, the numeric field is highlighted. In the Number Format column, double-click Numeric, and click Option . The Number Format window opens.

5. In the Number Format window, select Decimal places for Rounding, and click the Increment or Decrement arrow to set the number of decimal places. In this example, the number is 2. Click OK.

6. On the top ribbon, on the Fields tab, and click Save .

Note:
The saved changes in the attribute table are not reflected in the label. The numbers in the label must be rounded in the Label Class settings for the changes to be reflected on the map.

Round numbers in the feature layer label

1. On the Contents pane, select the feature layer.
2. On the top ribbon, under Feature Layer, click the Labeling tab, and click Enable Labeling .
3. In the Label Class group, click Expression  in the Field section. The Label Class - <layer_name> pane opens.

4. In Label Class - <layer_name> pane, ensure Arcade is selected for Language.
5. In the Expression text box, delete the existing value.
6. Under Functions, double-click Round().
7. Under Fields, double-click the numeric field. In this example, the field is LENGTH. Ensure the field value is inserted in the Round() function.
8. In the Expression box, next to the field value in the Round() function, type a comma (,) and the number of decimal places. In this example, the number of decimal places is 2.

Round($feature.<field_name>,<decimal_places_number>)

9. Click Verify  to validate the expression.
10. Click Apply.
