APL uses the term operator in Heaviside’s sense as a moderator of a function as opposed to some other programming language's use of the same term as something that operates on data, ref. relational operator and operators generally.
As of 2010, Unicode allows APL to be stored in text files, published in print and on the web, and shared through email and instant messaging. Entering APL characters still requires the use of either a specific input method editor or keyboard mapping, or of a specific touch interface. APL keyboard mappings are available for free for the most ...
APL (named after the book A Programming Language) [3] is a programming language developed in the 1960s by Kenneth E. Iverson.Its central datatype is the multidimensional array.
Conceptual questions or conceptual problems in science, technology, engineering, and mathematics (STEM) education are questions that can be answered based only on the knowledge of relevant concepts, rather than performing extensive calculations. They contrast with most homework and exam problems in science and engineering that typically require ...
Alan Jay Perlis (April 1, 1922 – February 7, 1990) was an American computer scientist and professor at Purdue University, Carnegie Mellon University and Yale University. He is best known for his pioneering work in programming languages and was the first recipient of the Turing Award .
It has the same value as the negation operator applied to 123 but is a different concept. I'll stick this in if nobody has a better idea. Also a computery side might be an idea too. APL has negative numbers e.g. − 123 separate from negated integers and IEEE has -0. Dmcq 18:43, 21 January 2009 (UTC)
In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution.
The concepts (A i, B i) of a context K can be (partially) ordered by the inclusion of extents, or, equivalently, by the dual inclusion of intents. An order ≤ on the concepts is defined as follows: for any two concepts (A 1, B 1) and (A 2, B 2) of K, we say that (A 1, B 1) ≤ (A 2, B 2) precisely when A 1 ⊆ A 2.
