If the author is here, have you tested and can you comment on the precision of these different methods? I see the code uses some fast-math style approximations for a few operations. How does that compare to Newton-Raphson? And what was the termination criteria for Newton-Raphson… can the runtime be increased or decreased significantly by adjusting the threshold a little?

Need a way to create letter transformation and number transformation !
