Given a good approximation, Newton-Raphson doubles the number of significant digits on each iteration (quadratic convergence). The above approximation provides about 4 bits of accuracy (max error: 6% or ~1/16), so 3 Newton-Raphson iterations are required for single and 4 iterations for double precision.
