How to improve fixed point square-root for small values

http://stackoverflow.com/questions/8721022/how-to-improve-fixed-point-square-root-for-small-values

greater than a few kilometers but is very poor at smaller distances. The worst case being when the two points are equal or near.. 194 meters while I need precision of at least 1 metre at distances 1 metre. By comparison with a double precision floating point.. but that will not solve the problem for small non zero distances where the error starts at 194 metres and converges toward zero..
