WebMar 13, 2015 · Here's an implementation of square root function using Newton-Raphson method. The basic idea is that if y is an overestimate to the square root of a non-negative real number x then x/y will be an underestimate, or vice versa, and so the average of these two numbers may reasonably be expected to provide a better approximation. WebJul 4, 2010 · Your usual c++ intrinsic sqrt () would probably beat it hands down.
