The BigNumber project is a testbed for developing various implementations of big integers and rational numbers in C#. The main guideline of the project is simplicity of use, robustness and completness of the libraries. The library will provide various algorithms for general use.

A library written in vanilla Lua that can handle massive numbers, while still being efficiently fast.

Factorial-base representation of rational numbers

This python library helps store massive integers by using a gzipped-string representation in memory. It makes storing and comparing huge integers fast and lightweight, while gracefully falling back to normal integer operations when math is needed. It works as a drop-in replacement for int.This library is not magic, I have not somehow figured out how to break the pigeon-hole principle. It simply exploits the fact that most large numbers we work with in real life are not 100% random, and either contain repeating patterns (like lots of 0's) or can be represented compactly by using using notations like scientific notation, factorial notation, knuth's up-arrow notation, etc..

CODE SAMPLE (C++): BigInteger is mostly an exercise in operator overloading and abstraction. The problem it solves is to compute very large numbers like big factorials or any operation that involves integer numbers of any size.
