RS03881: USING DECISION ENGINE, PRIMITIVE NUMERIC EXPRESSIONS ARE BOXED TO JAVA.LANG.DOUBLE WHEN JAVA.LANG.NUMBER IS EXPECTED

21.0.2-WS-CP4BA-IF009
21.0.3-WS-CP4BA-IF007

APAR status

• Closed as program error.

Error description

• When using Number as type in the BOM:
  - in CRE, this type gets translated for the execution into
  Integer or Double based on the value format. If value contains
  decimal then it gets converted to Double, otherwise converted to
  Integer.
  - but in DE, this type always get translated into Double.
  
  For ease of migration from Classic Rule Engine (CRE) to Decision
  Engine (DE), the conversion should be the same using both
  engines.
