Binary square root algorithm
WebIf 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. For example, for sqrt(50) you'd get 7, since 8*8 would be … WebOtherwise, it ends after a finite number of steps. y is a digit from 0 to 9. dd is the group of digits so far acquired in the square root operation while 2dd is dd times 2. Example: Finding the square root of 1089: 0..10; 10 03 x 3 = 9; 10 - 9 = 1; 1..89; 189. 3 x 2 = 6; 63 x 3 = 189; 189 - 189 = 0 done. The square root of 1089 is 33

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.
