Dyalog APL is implemented primarily in [[wikipedia:C (programming language)|C]] with some parts implemented in [[wikipedia:C++|C++]] in order to use [[wikipedia:C++#Templates|templates]]. C [[wikipedia:Intrinsic function|intrinsics]] are used to access instruction set extensions. Some architecture-specific [[wikipedia:Assembly language|assembly]], both compiled separately and inline from C, is used for functionality like [[wikipedia:Status register|exception flags]] which is not easily accessible in C. Prior to [[Dyalog APL versions#17.0|version 17.0]], assembly was also used for vectorized arithmetic. In 17.0, this code was replaced by a new C++ implementation. | |||

This code is also used for operations involving the scalar dyadics [[Plus]], [[Minus]], [[Times]], [[Divide]], [[Maximum]], [[Minimum]], and [[comparison function]]s, as well as some functions derived from operators applied to these functions, such as the [[Outer Product]] and [[Inner Product]]. | ||
