The algorithm computes 1/√x by performing the following steps:

    Alias the argument x to an integer, as a way to compute an approximation of log2(x)
    Use this approximation to compute an approximation of log2(1/√x)
    Alias back to a float, as a way to compute an approximation of the base-2 exponential
    Refine the approximation using a single iteration of the Newton's method.

The algorithm computes 1/√x by performing the following steps:
    Dark, dark magic.

x = (2**a)*(1+b)
log x = a + log(1+b)
