Long Integers: Basis Arithmetic and Data Types

Volume 6, Issue 2
Spring 1996

Long-integer arithmetic is a fundamental part of symbolic computation. This article introduces the fundamentals of long-integer calculations by implementing a prototype system in Mathematica. Our code is strictly procedural and could be translated into C or assembler easily. The tools needed are arrays that behave like arrays in procedural languages, as well as tools for software testing and debugging.
