These BASIC dialects are optimised for calculator use, combining the advantages of BASIC and keystroke programming. They have little in common with mainstream BASIC. [4] [5] [6] The version for the Ti-89 and subsequent is more fully featured, including the full set of string and character manipulation functions and statements in standard Basic.
Backside of the above HP-12C with some use cases with the respective keys to be pressed for frequent tasks from the field of finance A financial calculator or business calculator is an electronic calculator that performs financial functions commonly needed in business and commerce communities [ 1 ] (simple interest, compound interest, cash flow ...
Postfix conditional testing may be accomplished by using the IFT ("if-then") and IFTE ("if-then-else") functions. IFT and IFTE pop two or three commands off the stack, respectively. The topmost value is evaluated as a Boolean and, if true, the second topmost value is pushed back on the stack.
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [1] [2] [3] On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
A list is nothing more than an aggregate of linked conses. A variable that refers to a given list is simply a pointer to the first cons in the list. Traversal of a list can be done by cdring down the list; that is, taking successive cdrs to visit each cons of the list; or by using any of several higher-order functions to map a function over a list.
A dictionary coder, also sometimes known as a substitution coder, is a class of lossless data compression algorithms which operate by searching for matches between the text to be compressed and a set of strings contained in a data structure (called the 'dictionary') maintained by the encoder. When the encoder finds such a match, it substitutes ...
BASIC (Beginners' All-purpose Symbolic Instruction Code) [1] is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers.
The capabilities of a modern scientific calculator include: Scientific notation; Floating-point decimal arithmetic; Logarithmic functions, using both base 10 and base e; Trigonometric functions (some including hyperbolic trigonometry) Exponential functions and roots beyond the square root; Quick access to constants such as π and e
