bigint is a C++ library which can handle Very very Big Integers. It can calculate factorial of 1000000... it can go any big. It may be useful in Competitive Coding and Scientific Calculations which deals with very very large Integers. It can also be used in Decryption process. It has many inbuilt functions which can be very useful.

BeeNum is an arbitrary-precision arithmetic library.

BigInt in C++

A header-only C++ library provides a arbitrary-fixed-width integer type called bigint. It supports both signed and unsigned numbers with a customizable bit-width. The class implements a wide range of arithmetic, bitwise, and comparison operators, making it suitable for tasks that require precise control over large integers.

A fast Big Integer library written in C++23 providing many useful functions, like fast modular power, sqrt(), very fast log(), gcd(), perm(), comb(), etc...

BigInteger in C++

Built a Big Integer library, similar to what we have in Java as BigInteger.Library provide functionalities to store arbitrarily large integer and perform basic math operations like addition, subtraction, multiplication, Fast exponentiation, GCD of 2 integers and factorial.

Includes C++ Implementation of Data Structures and Algorithms.

BigInteger class is used for the mathematical operation which involves very big integer calculations that are outside the limit of all available primitive data types. In this way, BigInteger class is very handy to use because of its large method library and it is also used a lot in competitive programming.
