A '''dyadic function''' is a [[function]] with two [[argument]]s, one on the left and one on the right. It is one of three possible function [[ | A '''dyadic function''' is a [[function]] with two [[argument]]s, one on the left and one on the right. It is one of three possible function [[valence]]s; the other two are [[monadic]] and [[niladic]]. The term '''infix function''' or infix operator is used outside of APL to describe APL's dyadic function syntax. | ||
In APL, a single function can be both monadic and dyadic; such a function is called [[ambivalent]] or sometimes variadic. Function pages on the APL Wiki usually only describe one valence of an ambivalent function because the connection between the two may not be consistent across languages. In this case the function is described as dyadic even though it may only be half of an ambivalent function. | In APL, a single function can be both monadic and dyadic; such a function is called [[ambivalent]] or sometimes variadic.
