Boolean

In most computer programming languages, a Boolean data type is a data type with only two possible values: true or false.

Related to this, Boolean (named after George Boole) may also refer to:

• Boolean algebra, a logical calculus of truth values or set membership
• Boolean algebra (structure), a set with operations resembling logical ones
• Boolean domain, a set consisting of exactly two elements whose interpretations include false and true
• Boolean circuit, a mathematical model for digital logical circuits.
• Boolean expression, an expression in a programming language that produces a Boolean value when evaluated
• Boolean function, a function that determines Boolean values or operators
• Boolean model (probability theory), a model in stochastic geometry
• Boolean network, a certain network consisting of a set of Boolean variables whose state is determined by other variables in the network
• Boolean processor, a 1-bit variable computing unit
• Boolean satisfiability problem
