WebIn the case of a boolean, # there's two possiblities, `true` and `false`. Each implementation accepts as # input a candidate transformation for each data constructor, selecting one of # them. # For booleans, our encoding resembles if-then-else conditional expressions. A # boolean can be treated as a predicate that accepts two arguments: a "then" WebChurch booleans are the Church encoding of the boolean values true and false. Some programming languages use these as an implementation model for boolean arithmetic; …
WebDec 25, 2024 · Church encoding is a scheme by which any calculable operator and its data (operands) can be expressed purely in terms of functions.
