Is it possible to compute the 53-bit logarithm and improve it
iteratively? I don't know the standard way of computing logarithms
numerically; since its a transcendental function, I guess there's no
convenient newton iteration (but if exp is easier to compute, there
ought to be an iteration using exp evaluation and newton).
