A complex relation performs a comparison between the values of two complex expressions. Because one of the forms of a complex expression is an arithmetic expression, the complex relation can also be used to compare a complex value and an arithmetic value. In a complex relation, the only allowed relational operators are =, EQL, ^=, and NEQ.
