This is a Reverse Polish Notation calculator, loosely modelled on the Hewlett-Packard HP-16C, a machine which is targeted at programmers who work in different number bases. It provides floating point arithmetic, and integer arithmetic in four number bases - decimal, hexadecimal, octal and binary. Integers can be 8-bit, 16-bit or 32-bit, signed or unsigned. It includes mathematical, trigonometric, financial and statistical functions, constants, conversions, logical functions, user-defined formulae and memories for intermediate storage. All functions are completely screen driven for speed of use.
