Open Source FreeBSD Calculators

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.

Fast calculator is fast and simple calculator with many functions on java.

The Fung-Calc is an advanced, yet easy to use graphing calculator that supports graphing in both 2D and 3D. Several different plot types are available and graphs can be animated.

Crossplatform utility that calculates network address, broadcast address, etc... by given IP and mask.

Can calculate mathematical expression. It have a module system witch make it very easy to add own functions. Other features are a graph painter and a tiny programming language designed too make it easy too write small mathematical tools.

Phone Call Cost is a program that in the end, aims to be able to pull length of call time from a phone that displays such information and multiply it by a known rate (given to the program via the UI (or hard coded in by the end user)) and return the cost
