finding square roots

here is an interesting example function for javascript. while not needed, it serves to demonstrate the procedure using javascript.

function sqrt(number){
  var guess = 2, old=0;
  for(var step=0;step<128;step++){
    old = guess;
       guess = (guess + (number/guess)) / 2;
    if(old===guess){break;}
   }
  return guess;
}
