This operation is using the Field Calculator in ArcGIS Pro 2.1.
I am trying to calculate the Polsby-Popper Score for Congressional Districts. I have calculated the Geodesic Area and Geodesic Perimeter for each feature using this formula:
(12.56637 * !AREA_GEO!) / (!PERIM_GEO! ^ 2)
It is returning the error:
ERROR 000539: Traceback (most recent call last): File "", line 1, in TypeError: unsupported operand type(s) for ^: 'float' and 'int'
I am not sure what exactly this error means.
