An extensive math library for JavaScript and Node.js

Small portable multiple-precision unsigned integer arithmetic in C

A replacement for decimal.js for incremental games who want to deal with very large numbers (bigger in magnitude than 1e308, up to as much as 1e(9e15) ) and want to prioritize speed over accuracy.

A Javascript numerical library to represent numbers as large as 10^^1e308 and as small as 10^-10^^1e308. Sequel to break_infinity.js, designed for incremental games.

Pattern matching language for transforming complex tree-structured data (strings, XML, JSON, algebraic expressions). Built-in symbolic algebra, backtracking, and exact arithmetic. Portable C99.

(TS) Tiny 2kb, zero deps, infinite precision: Biggest for all your big integer + big decimal needs.

BeeNum is an arbitrary-precision arithmetic library.

Algorithm for high-speed multiplication of LARGE numbers

The Big Number C library is a C library for arbitrary precision arithmetic. It can be used to perform arithmetic operations on numbers of arbitrary size. It is written in C and is designed to be portable and efficient. You can work with numbers of any size, and the library will automatically allocate memory as needed.
