Feedback on fast sqrt

Above the graph, I think there's a typo: instead of L = 23, it should say L = 2^23. It would be nice to also mention that a multiplication by a power of two is equivalent to a left shift (hence where the I_x bit pattern comes from). The bias also comes out of nowhere: it should be briefly explained that IEEE exponents are shifted by 2^(e_x-1)-1. It's also be nice to have labels on the graph axes as I'm still not 100% sure what they mean. I believe vertical=binary representation while horizontal=float number.

Thanks, clarified all that.

Awesome!
