IQ56 RPN Calculator

IQ56 RPN Calculator

The IQ56 RPN Calculator is a simulation of the HP45 calculator written in VB .NET 2.0. Numeric results are not 100% identical to the original as the floating point on the PC (double precision) is greater than that of the original so more digits of mantissa are available for the calculations to use.

Originally this was prepared for use on a "Pocket PC" using the .NET Compact Framework 1.1. I am considering moving it to the .NET Compact Framework 2.0 and then releasing that version as well.
