Programming algorithms...

I rather like algorithms especially those that operate in computers and
calculators, etc. Very practical, ingenious mathematics which is, for the
most part, fairly availiable to a trig student. I even demo Newton's method
for square roots in Algebra I for fun. Along that line I just got a great
book "Projects in Scientific Computation" by Crandall. Great!!!

But my question. Has anyone ( outside of a programming class) ever presented
the algorithms utilized in a calculator ( of course, the precise ones might
be difficult to pinpoint) as an example of very practical mathematics? For
fun I have given problems that are essentially impossible on a calculator
and quite easy with pencil and paper to indicate some of what is going on. And
the business with Intel ( I mean how it was determined that there was
an error, what it was, and how to 'patch' it) was quite interesting.

I remember when I first realized that numbers in the Handbook of Chemistry
and Physics were actually computed by fairly accomplished mathematicans :).
Fascinating history!

There is even a history of multiplication and division algorithms which
appear and reappear at all levels in mathematics.
