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.
