The most bananas paper, how to raise to a power using a table, a multiply, and operand modification.

So, you want a reciprocal sqrt? Take your input operand X, split it into two parts X1 and X2, use the X1 to calc this polynomial C', flip some bits in X2, reassemble X1 and X2 into X', multiply C'*X' and voila, 6 or 7 decimals of precision!

It's like alien technology, how the hell is it so good?
