Effect

In Comparison expressions, two or more operands are combined to a relational expression using a comparison operator. A truth value is determined as the result of the comparison.

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

When a built-in 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.

Typical use of a logical expression, here a comparison of a built-in function with a literal, in an IF statement.
