TRURL is a suite of desktop calculators with reverse Polish notation (RPN) written in Object Pascal. Additionally, it comes with a free reusable class library (RPN Engine) as a toolbox for creating your own calculator. TRURL is an acronym for "TRURL is a Reusable Universal RPN Library". Class Libraries: • RPN Engine: Full-featured calculation engine for Pascal-based RPN calculators • Segmitator: Library for virtual seven-segment displays Applications: • TRURL A: Simple demo app for the RPN Engine • TRURL B: RPN calculator in the design of the famous calculators by Dieter Rahms for Braun • TRURL G: Desktop RPN calculator inspired by the UI of the DSKY unit of the Apollo Guidance Computer (AGC)

An advanced calculator program that supports programming/scripting, a variety of mathematical functions, and a graphing utility.

In addition to standard calculator functions, you can perform trigonometric calculations, binary, decimal, hexadecimal. Are included in the calculation of the programs tables, fibonacci, factorial, random number, charting, statistic basic, fast random generator number 1-90, generation and a system for fast calculation of the percentage, calculating the perimeter and area of plane geometric figures. This is also a program to create constant and recall among other functions is also a mini file editor text.
