**Further Casio Applications for Inside
Your Calculator**

This file contains new applications that supplement the text
* Inside Your Calculator*:

The algorithms **BIGMULT** and **BIGDIV**
are developed through comparison with our standard decimal algorithms for carrying
out similar procedures with one and two-digit numbers. This provides insights
into the important and rarely explained bases for these procedures. At the same
time the programs give your calculator processing power that for these applications
parallels those of Mathematica and Maple.

The program **BIGMULT**,
which also appears as Appendix L in * Inside Your
Calculator*, describes in detail a program that will give you
the ability to multiply numbers with products of up to 400 digits.

The program **BIGDIV** extends
the ideas of BIGMULT to division, The resulting program will handle calculations
whose divisor, dividend and quotient may each have up to 400 digits.

The program **BIGDIV** can be very slow, however. The reason:
correcting the partial quotient when it turns out to be too large is done by
reducing the trial quotient one at a time. With large numbers this can slow
the process considerably. A way around this is described in Donald Knuth's * The
Art of Computer Programming*, volume 2 (
