Selectable-Precision Calculator

This module provides a desk calculator with user-selectable precision. It is intended to make it easy for students to experiment with the effects of finite-precision arithmetic, for example doing homework problems that require a fixed (usually fairly short) precision.

The user selects any desired precision from 1 to 25 decimal digits. The calculator then performs the usual arithmetic operations in the chosen (fixed) precision.
