{{Short description|Expression in a computer program}}
In [[computer science]], a '''Boolean expression''' is an [[Expression (programming)|expression]] used in [[programming language]]s that produces a [[Boolean value]] when evaluated. A Boolean value is either '''true''' or '''false'''. A Boolean expression may be composed of a combination of the Boolean constants '''True/Yes''' or '''False/No''', [[Boolean data type|Boolean-typed]] variables, Boolean-valued operators, and [[Boolean-valued function]]s.<ref>{{citation
