APL syntax and symbols : ウィキペディア英語版 | APL syntax and symbols
The APL programming language is distinctive in being ''symbolic'' rather than ''lexical'': its primitives are denoted by ''symbols'', not words. These symbols were originally devised as a mathematical notation. APL programmers often assign informal names when discussing functions and operators (for example, (unicode:product for ×/)) but the core functions and operators provided by the language are denoted by non-textual symbols. ==Monadic and dyadic functions== Most symbols denote ''functions'' or ''operators''. A ''monadic'' function takes as its argument the result of evaluating everything to its right. (Moderated in the usual way by parentheses.) A ''dyadic'' function has another argument, the first item of data on its left. Many symbols denote both monadic and dyadic functions, interpreted according to use. For example, (unicode:⌊3.2) gives 3, the largest integer not above the argument, and (unicode:3⌊2) gives 2, the lower of the two arguments.
