A toy arbitrary precision integer arithmetic library written in C++. Currently, it features addition and subtraction implemented in linear time, as well as multiplication in subquadratic time using Karatsuba's algorithm. This is designed only for educational purposes.
Numbers are represented in base 10, stored using a std::vector<int> object for digits and a bool for sign.
To build the project using CMake, follow these steps:
mkdir build
cd build
cmake ..
makeRun ./test.
