## How do you do square root algorithm?

To find the square root of S, do the following:

1. Make an initial guess. Guess any positive number x.
2. Improve the guess. Apply the formula x1 = (x + S / x) / 2. The number x1 is a better approximation to sqrt (S).
3. Iterate until convergence. Apply the formula xn+1 = (xn + S / xn) / 2 until the process converges.
