arithmetic-type/uint64

@arithmetic-type/uint64 is a JavaScript library that provides 64-bit unsigned integer arithmetic and logic operators, implemented using big endian arrays of two signed 32-bit integers. It's designed for developers working on cryptographic algorithms, hashing functions, or other applications requiring precise 64-bit integer operations in JavaScript, where native number types are insufficient due to precision limitations. The library is particularly useful for projects like js-hash and serves as a counterpart to the 32-bit uint32 library.
