Faster Cube Root IV

Previously, I created a few posts on the subject of fast cube root calculation (1,2,3); also, n-th root approximation (1). I spent a little time collecting these thoughts into a more cohesive form, which may be found by following this link:

In Search of a Fast Cube Root

Also included is code to approximate cube roots by various means (bit hack approximations, Newton-Raphson, Halley's method) and associated performance results.
