Boolean data type

In <a href="/facts/Computer_science/lN3pEyPz">computer science</a>, the Boolean (sometimes shortened to Bool) is a <a href="/facts/Data_type/fcx5hgVL">data type</a> that has one of two possible values (usually denoted true and false) which is intended to represent the two <a href="/facts/Truth_value/SY4e2w8l">truth values</a> of <a href="/facts/Logic/8JnpJLtt">logic</a> and <a href="/facts/Boolean_algebra/VkCToAmg">Boolean algebra</a>. It is named after <a href="/facts/George_Boole/fWJT2rek">George Boole</a>, who first defined an algebraic system of logic in the mid 19th century. The Boolean data type is primarily associated with <a href="/facts/Conditional_(computer_programming)/8gDQTqUD">conditional</a> statements, which allow different actions by changing <a href="/facts/Control_flow/2XTDfErC">control flow</a> depending on whether a programmer-specified Boolean condition evaluates to true or false. It is a special case of a more general logical data type—logic does not always need to be Boolean (see <a href="/facts/Probabilistic_logic/4MIPxPIJ">probabilistic logic</a>).
