Is there a book like this on scientific/engineering math?

Actually, you could probably write a book on Numerical Methods, by going through section of the code for the WP34S.

Back in my University days, I can recall studying Newton & Halley methods for square roots. Division? Logs? Don't make me laugh.

I have a copy of Knuth's "Semi Numerical Methods" but either I'm slow or that book is too deep. Whatever you get, I hope you can "dip in" to different topics without getting overwhelmed.
