The language APL\360 of IBM (August 1968) and the other APL dialects that have followed it have used a single "|" as a monadic prefix operator that computes the absolute value and also as a dyadic infix operator that computes the remainder of the division (but with the operand order reversed in comparison with the language C, which is usually much more convenient, especially in APL, where this order avoids the need for parentheses in most cases). |
