With the Form Calculation profile, expressions can be written to update a form value based on expression logic. This profile is used when defining form calculations in Field Maps. When the script is evaluated, the return value is cast to the field type of the output value. It is best practice to handle casting within the script for full control of casting behavior to Number, Date, or Text return types.
Context
The following products implement this profile:
Spatial reference
The spatial reference of the map in which the expression executes determines the execution context's spatial reference.
Time zone
The time zone of the map in which the expression executes determines the execution context's default time zone.
