Programmable calculator. Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make ...
bc first appeared in Version 6 Unix in 1975. It was written by Lorinda Cherry of Bell Labs as a front end to dc, an arbitrary-precision calculator written by Robert Morris and Cherry. dc performed arbitrary-precision computations specified in reverse Polish notation. bc provided a conventional programming-language interface to the same capability via a simple compiler (a single yacc source ...
A modern scientific calculator with an LCD. An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the ...
For example, take this line of TI-BASIC code: Disp [A]. In a conventional programming language, this line of code would be nine characters long (eight not including a newline character). For a system as slow as a graphing calculator, this is too inefficient for an interpreted language. To increase program speed and coding efficiency, the above ...
Calculator input methods. There are various ways in which calculators interpret keystrokes. These can be categorized into two main types: On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression. [4][5][6] There are various systems for typing in an expression ...
A software calculator is a calculator that has been implemented as a computer program, rather than as a physical hardware device. They are among the simpler interactive software tools, and, as such, they provide operations for the user to select one at a time. They can be used to perform any process that consists of a sequence of steps each of ...

Casio BASIC is a programming language used in the Casio calculators such as the ClassPad, PRIZM Series, fx-9860G Series, fx-5800P, Algebra FX and CFX graphing calculators. It is also known as "BasicLike" in some models. This programming language has nothing to do with the more or less standard BASIC, which incorporated from the beginning of the ...
