FEEL Data Types
Heads Up!
This page provides information on the legacy FEEL Engine, that was used before the current Scala-based FEEL Engine was integrated into Camunda 7.
The Camunda DMN engine supports the following FEEL data types.
String
FEEL supports Strings. They must be encapsulated in double quotes. They support only the equal comparison operator.
Numeric Types
FEEL supports numeric types like integer. In the Camunda DMN engine the following numeric types are available:
- integer
- long
- double
Numeric types support all comparison operators and ranges.
Boolean
FEEL supports the boolean value true and false. The boolean type only
supports the equal comparison operator.
Date
FEEL supports date types. In the Camunda DMN engine the following date types are available:
- date and time
To create a date and time value, the function date and time has to be used
with a single String parameter. The parameter specifies the date and time in
the format yyyy-MM-dd'T'HH:mm:ss.
Date types support all comparison operators and ranges.
