PDQ Algorithm

Description:PDQ finds best rational approximations, with infinite precision. This means it finds the two smallest integers whose ratio is equal to some target real number plus or minus some desired tolerance. In other words, it finds the simplest fraction in any given interval. Unlike other methods, it always finds the unique best answer, and uses the infinite precision of CAS long integers.
