Description

The lexical constants true and false evaluate to a value of type Logical. Expressions containing operators that compare values (for example equal or less than) also evaluate to a logical. Logical expressions can be combined with logical "and" and logical "or" operators, and are evaluated in a short-circuited fashion.
