Some languagess, e.g., [[Perl]], have two sets of boolean operators, with identical functions but different precedence. Typically these languages use '''and''', '''or''' and '''not''' for the lower precedence operators.
Some programming languages derived from [[PL/I]] have a bit string type and use BIT(1) rather than a separate boolean type. In those languages the same operators serve for boolean operations and bitwise operations. The languages represent OR, AND, NOT and EXCLUSIVE OR by "|", "&", "¬" (infix) and "¬" (prefix).
