#82833 - Calculating Square Roots Responding to: ???'s previous message |
Hi Prahlad,
You might try this, from page 921 of "Numerical Recipes in C," 2nd Edition (Cambridge University Press). U_(i+1) = 0.5 * U_i * (3 - V * [U_i]^2) It says that U_{inf} converges quadratically to V^(-0.5), (the reciprocal of the square root of V), so that a final multiplication by V will yield V^0.5 (the square root of V). The point is that if it converges quadratically, that should be pretty fast. Good luck. |
