I am attempting to make an initial approximation for the inverse algorithm (1/x)
The problem is finding the initial approximation. An exponential equation seems to fit the best
http://www09.wolframalpha.com/input/...%29%28.5^x%29 I chose .5, because in binary, dividing by two is as simple as shifting to the right. Is there any other way to make a close approximation that is better than .5^n?
