Square Root using Binary Search :: AlgoTree

Many iterative square root algorithms require an initial seed value. The seed must be a non-zero positive number; it should be between 1 and , the number whose square root is desired, because the square root must be in that range. If the seed is far away from the root, the algorithm will require more iterations. If one initializes with (or ), then approximately iterations will be wasted just getting the order of magnitude of the root. It is therefore useful to have a rough estimate, which … WebAug 21, 2024 · If we know all but the last one bit of the square root of a number, then we can get to the remaining bit by subtracting 4 times the square of the number formed by the other bits from the square of the … the poison dragon legend of asuraWebIf you need the square root of X, the closest you can get is the largest integer whose square is less than or equal to X.
