NOToperatori

NOToperatori is a term used to describe a family of negation operators in logic and computer science that generalizes the basic notion of logical negation beyond simple true/false propositions. The concept encompasses unary negation that inverts a value as well as variants that apply to different data kinds, such as bit patterns, predicates, and multi-valued logics.

In boolean contexts, a NOT operator yields the opposite truth value: true becomes false and false becomes true. In bitwise contexts, the operator inverts each bit of an integer. In programming languages, negation can target a predicate (yielding the opposite condition) or a bitwise complement of an integer. In extended logics, such as three-valued or fuzzy logic, NOT is defined as a function on a lattice of truth values, often satisfying certain axioms and interacting with other operators through generalized laws.

Algebraic properties commonly associated with NOToperatori include De Morgan’s laws, which describe how negation distributes over conjunction and disjunction: NOT(A and B) equals (NOT A) or (NOT B), and NOT(A or B) equals (NOT A) and (NOT B). These relationships have direct analogues in both boolean algebra and bitwise logic, though their exact form can depend on the underlying logic or data type.

Notation and usage vary by domain and language. Common forms include the words not or logical symbols, the exclamation mark !, or the tilde ~ for bitwise negation. The term NOToperatori is a generic, coined way to refer to this family rather than a standardized standard term in formal literature.
