Effect

Comparison expressions join two or more operands using a relational operator to make a relational expression and produce a logical value as the result of the comparison.

operand1, operand2, and operand are general expression positions, which means that the following can be specified:

When a predefined function, a functional method, or a constructor expression is specified, its return value or result is used as an operand. When a calculation expression is specified, its result is used. A single operand can be compared with all single operands listed in the comparison rules for single operands. A calculation expression can be compared with all single operands or comparisons listed in the comparison rules for calculation expressions.
