Arbitrary Precision - Easy-to-use C++ Library for Long Integer Arithmetic

Currently, there are a lot of libraries that offer arbitrary precision arithmetic types (be it integer or float) with a complete interface, high performance, and reliability (GNU MP, Boost.Multiprecision, Crypto C++). However, adding them as a dependency to your project is not a single-step task. Small standalone libraries do exist, but they usually have certain flaws: the base is a power of 10, it is necessary to compile sources (.cpp), they are not reliably tested, and so on. This article introduces a new library, called Arbitrary Precision, which offers a reliable, flexible, and relatively fast long integer class.
