I apologize if it is not the proper newsgroup to ask but I need help. I implemented the Newton-Raphson method to calculate integer square root with the following code: int Sqr(int param) { int guess = 1, tmp; do { tmp = guess; guess = (guess + param / guess) / 2; } while (tmp != guess); return guess; } (Actually, I wrote it in ARM assembly but this is the idea.) Now the problem is that this code rounds DOWN to the closest integer; can someone tell me how to modify it to get properly rounded results? Please reply through E-mail.
