Turns out these two methods are being used in many approximation algorithms and real-time applications, including the one I mentioned.\r\nhttps://en.wikipedia.org/wiki/Methods_of_computing_square_roots\r\nhttps://en.wikipedia.org/wiki/Division_algorithm\r\n\r\nI am originally interested in algorithms for stepper motors. If you are so, I found two books used as references: https://www.amazon.com/dp/0198593856/\r\nhttps://www.amazon.com/dp/085296417X/\r\n\r\nI will also take a look at Numerical Recipes mentioned below.
