Church encoding boolean
WebChurch encodings are a very interesting development arising from lambda calculus. Church found out that every concept in programming languages can be represented using functions! everything from boolean logic, conditional statements, numbers (natural, integer, real, complex, imaginary), and even loops (infinite loops also)! WebLet’s first examine some of the encodings for the Church Boolean constants and operations. TRUE = λ x. λ y. x. FALSE = λ x. λ y. y. AND = λ p. λ q. ( ( p q) F A L S E) Note that AND is a curried function of the two variables p and q. The following slide show indicates how TRUE AND FALSE, which is ( (AND TRUE) FALSE) in curried form, is ...

Church Booleans are the Church encoding of the Boolean values true and false. Some programming languages use these as an implementation model for Boolean arithmetic; examples are Smalltalk and Pico. Boolean logic may be considered as a choice. The Church encoding of true and false are functions of … See more In mathematics, Church encoding is a means of representing data and operators in the lambda calculus. The Church numerals are a representation of the natural numbers using lambda notation. The method is … See more Church numerals are the representations of natural numbers under Church encoding. The higher-order function that represents natural number n is a function that maps any function $${\displaystyle f}$$ to its n-fold composition.
