Comparison operators

This table shows the valid combinations of types for comparison operators. To understand the calculation of the expression A > B, find the type of A in the Left Hand Side (rows) of each table. Find the type of B in the Right Hand Side (columns) if the table. Consult the numbered notes for the details of casting or conversion.

Note: The operator ~= evaluates using equalsIgnoreCase().

A casting, promotion, or conversion is not supported. Pega 7 Platform reports an error.
1

Permitted. Depending upon complexity of expression and intermediate conversions that may have occurred, use either the original ClipboardProperty String form or Java BigDecimal.
2

Permitted. Converts Integer > Double > Decimal until both operands have same type, then performs operation. (Convert directly to target type without performing additional intermediate conversions.)
3

Permitted. Converts to the preferred Java type (and if necessary, promote as described in note 2) and performs the operation.
4

Permitted. Converts to Java boolean and performs the operation.
5

Permitted. Evaluate using String.compareTo(). Note: This is not locale-sensitive.
