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 the Camunda Platform.
The Camunda DMN engine supports the following FEEL data types.
String
![String](../../img/string-type.png)
FEEL supports Strings. They must be encapsulated in double quotes. They support only the equal comparison operator.
Numeric Types
![Integer](../../img/integer-type.png)
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
![Boolean](../../img/boolean-type.png)
FEEL supports the boolean value true
and false
. The boolean type only
supports the equal comparison operator.
Date
![Date](../../img/date-type.png)
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.
