FEEL

Friendly Enough Expression Language is the language defined by the DMN standard.

You can find all the FEEL functions here and in the modeler under the LEARN ribbon.

You can find all the FEEL Basic types, operators, statements, intervals, extraction and filters here.

FEEL also offers an alternative dialect named B-FEEL (Business Friendly Enough Expression Language) which shares the same grammar as FEEL but alters the semantics to be friendlier and more intuitive toward non-IT users.
