I was finding out the algorithm for finding out the square root without using sqrt function and then tried to put into programming. 1 Start with an arbitrary positive start value x (the closer to the root, the better). For example, it is natural to expect that Newton's method will converge to the root nearest the initial guess. The result is the same no matter what method you use to find it. Steps A little while ago I wrote about the Babylonian method for approximating square roots with pencil and paper. Those who progress quickly can go beyond what's being taught them and those who are struggling likewise have all the time in the world to catch up. Heron’s Method is a remarkably simple and fast-converging method for approximating square roots that was known to the Babylonians. Square Roots by Pencil and Paper At some stage in our schooling each of us was taught how to extract square roots by "pencil and paper", using a method that vaguely resembles "long division", but this method is almost never actually used by anyone, presumably because (1) taking square roots is not a very common operation in daily life, and (2) we have calculators (and before them, sliderules If the number is not a perfect cube, the method is still useful in that we can find two consecutive integers between which the cube root lies.
