A boolean-valued function is a function of the type f : X → B {\displaystyle f:X\to \mathbb {B} } , where X {\displaystyle X} is an arbitrary set, where B {\displaystyle \mathbb {B} } is a generic 2-element set, typically B = { 0 , 1 } {\displaystyle \mathbb {B} =\left\{0,1\right\}} , and where the latter is frequently interpreted for logical applications as B = { f a l s e , t r u e } {\displaystyle \mathbb {B} =\left\{false,true\right\}} .
