This paper describes a single unified algorithm for the calculation of elementary functions including multiplication, division, sin, cos, tan, arctan, sinh, cosh, tanh, arCTanh, In, exp and square-root.Abstract:
This paper describes a single unified algorithm for the calculation of elementary functions including multiplication, division, sin, cos, tan, arctan, sinh, cosh, tanh, arctanh, In, exp and square-root The basis for the algorithm is coordinate rotation in a linear, circular, or hyperbolic coordinate system depending on which function is to be calculated The only operations required are shifting, adding, subtracting and the recall of prestored constants The limited domain of convergence of the algorithm is calculated, leading to a discussion of the modifications required to extend the domain for floating point calculationsread more

A multimicroprocessor approach to numerical analysis: An application to gaming problems
Robert E. McGill,John Steinhoff +1 more
TL;DR: It is argued that such a system in which the microcomputers operate with little mutual interaction should be effective for an important class of problems in numerical analysis, and estimates are given for the operation of the system on a problem in gaming theory.
