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.

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.
