The identity element for a specific reduction always depends on the operand, and may depend on the argument array prototype. Dialects differ in their support for such reductions. All define identity elements for most [[scalar functions#Standard scalar functions|scalar primitives]], and some stop there (e.g. [[SAX]]), while others (e.g. [[Dyalog APL]] and [[APL2]]) define identity elements for various [[mixed function]]s. | The identity element for a specific reduction always depends on the operand, and may depend on the argument array prototype.
