double negation in nLab

Weba Boolean. Description. The logical NOT (!) operator performs logical negation on an expression. Boolean values simply get inverted: !true === false and !false === true. Non-boolean values get converted to boolean values first, then are negated. This means that a double logical NOT (!!) can be used to cast any value to a boolean: Webnot b is the boolean negation of b. val (&&) : bool -> bool -> bool e0 && e1 is the lazy boolean conjunction of expressions e0 and e1 . If e0 evaluates to false, e1 is not evaluated. Right-associative operator at precedence level 3/11. val ( ) : bool -> bool -> bool e0 e1 is the lazy boolean disjunction of expressions e0 and e1 . shepherd fur jacket https://chantalhughes.com
