TILP (formerly GtkTiLink) can transfer data between Texas Instruments graphing calculators and a computer. It works with all link cables (parallel, serial, Black/Gray/Silver/Direct Link) and it supports the TI-Z80 series (73..86), the TI-eZ80 series (83PCE, 84+CE), the TI-68k series (89, 92, 92+, V200, 89T) and the Nspire series (Nspire Clickpad / Touchpad / CX, both CAS and non-CAS). The project is now managed on Github, https://github.com/debrouxl/tilp_and_gfm . It uses the libti* libraries, https://github.com/debrouxl/tilibs . Install script for *nix: https://github.com/debrouxl/tilp_and_gfm/blob/master/tilp/trunk/build/scripts/install_tilp.sh

GraphCalc is a very gui graphing calculator. It has been called a good replacement for a TI-85. It is a must for any high school math student.

A simple CPU simulator whose goal is to make assembly learning easier. This goal is reached giving a simple calculator, called ENIAC, with a simple CPU, called vCPU. The vCPU's instructions are very simple and easy to understand.

BigAl is a free open source and platform independent software for calculating really BIG numbers. It supports not only standard arithmetic, but also exact period determination, predefined factorials, fibonacci with seeds, factorization, nth root, etc

This is a Reverse Polish Notation (RPN) Fraction Calculator. It works like any other RPN calculator, except that it operates on fractions instead of decimal numbers. Decimal number entries are not permitted. Whole numbers are permitted.

Calculator software helping to determine L-T4 and L-T3 substitution dosage according to the algorithms provided by the European Thyroid Association (ETA).

X-Bc (formerly: xbc) is a graphical user interface to the command line calculator bc. All Inputs and Outputs stays visible for editing and comparing. Functionality: trigonometry, number-theory, exponential funcs, scientific constants, primenumbers ...

LCalc is a calculator for logic expressions. It support all standard logic operators (and,or,not,xor,...) and any user-defined operators . Features include generation of value table from formula and vice-versa.

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.

This is a simple C# command line calculator. It evaluates arithmetic expressions and functions. Easy to extend. Features include factorials, powers, brackets, bracket normalization, polish notation, factorization, fields, and advanced error reporting.

Breaks down the research process into pre-defined steps. Users enter a start date and end date for an assignment and the Assignment Calculator will compute the dates s/he needs to complete each step. Written by the University of Minnesota Libraries.

With BinaryCrypt, you can convert between regular text, binary, hexadecimal, octal decimal and decimal. You can convert only decimal (as of right now) to any base up to base 64. You can also save your converted text to a file or open a converted text file to decrypt the message, and perform basic arithmetic in binary. The git repo for the C# code is located at: https://github.com/m1r4g3/BinaryCrypt-.Net

Applications for mobile phones with Java installed (KVM MIPS 2), which functions as a calculator to solve basic problems offered to scientists of computing.

This project implements calculations for the Climate Equity Reference Project's Calculator (CERc).

System independent command line calculator written in C (C99 standard). Expression is first converted to Reverse Polish Notation and then evaluated.

A simple multi-platform DXM dosage calculator. Written in Java.

EVAlgebra , symbolic Clifford algebra calculator (geometric algebra) , is an Eigenmath adaptation. EVAlgebra support space dimension from 1 to 4 with arbitrry signature. It is fully documented at evalgebra.org. You may write your own scripts to resolve specific problem.

Evrika is a science simulator and advanced calculator, which is based on modules. Modules are libraries containing definitions of concepts that can be used in the simulation. By definitions we mean properties, actions, reactions, etc. Evrika is used for creating both simulations and modules, so you can build your own module of elements, then use them to create virtual experiments and simulations. Also, you can make advanced calculations. Evrika is basically an executable that reads and interprets code, outputing result. Each new version will offer new possibilities to define your elements and use them, so it is important to always have the last release. Of course, Evrika is backward-compatible, cross platform and free to use. In the near future an advanced editor and viewer will be created, so you can better manage your code and view the results.

GCalc is mathematical graphing calculator system in Java

The Grade Point Average Calculator is a web-based script that will calculate a grade point average based on the American system. Currently including calculation options for high school; middle shool and college versions are in development.

A PHP program that graphs in y= format. GD graphics library needed.

A simple on-line calculator for high mathematical problems Version 0.1 will be able to manage with matrixes

This terminal app runs on PCs or laptops running OSX or GNU/Linux. It attempts to mimic the functionality of an HP ReversePolishNotation [RPN] calculator with the added enhancement of interval output. So along with your answer, you get a good idea of its trustworthiness. This app uses GAOL, a C++ library to perform arithmetic with floating-point intervals.
