Open Source C++ Calculators - Page 4

A freeware Qt based project which targets a Calculator which has views of bin/dec/hex in the same window. I have missed this feature in legacy calculators and some of the colleagues asked about it too, hence the origin of the idea.

DOFView is a "Depth of Field" Calculator. It is a small application written in C++/Qt for Window and Linux to evaluate the effect of the focal, subject distance, and the f-Number change, on the depth of field. DOFView will report near and far distance limits, hyperfocal, total DoF etc., both in textual or graphical format. A simulation of what can be seen in the camera viewfinder is also shown in 3D. The application was inspired by my Nikon D5100, even if the user can set information and use this program selecting among hundreds of compact or DSLR camera models.

Calculate the concentration of Urea or Guanidine in solution from the measured refractive index of the sample.

Software project for networks to perform distributed calculations

Kexpcalc is an experience calculator and NPC generator for D&D 3.5. It also includes an item creation calculator (scrolls, potions, wands, and staffs).

Dog Age Calculator simply tells you your dog's age in "dog years" when you input it's "human age". Also, this is my first C++ project. Dog Age Calculator doesn't have GUI, so it runs in Terminal.

Easy Funktion is an easy to use function plotter that supports complex numbers as well as real numbers. Additional features are equation solving, approximation functions and a built in pocket calculator.

This project introduces a console application designed for functional emulation of the USA old calculator series Wang 700 and their USSR derivatives 15VSM (15ВСМ). The main goal of the project is emulation of those models made in Soviet Union: 15ВСМ-5, 15ВМ16/32/128 - which are also known as D3-28 (Д3-28). The choice of them is due to the extremely strong and authentic CPU command set developed by Soviet engineers as a superset around the original Wang 700's command set. While Wang 700 were just programmable calculators, Soviet machines were almost complete computers taking into account their advanced CPU command set, huge RAM volume, ability to work with wide set of peripheral devices including the video terminal 15IE (15ИЭ) and existence of BASIC and other programming languages written as loadable applications. Still I consider them as calculators also due to some aspects exclusively specific to calculators. The project is intended for research and education purposes.

End of Day Daily Tracking Calculator. A quick and dirty text based calculator designed to give you week to date sales, labor cost, inventory over/shortage and ext.

A scientific calculator with the possibility to propagate errors.

Euro NCAP Calculator is a GUI based tool, developed in Qt-Open source, to calculate EuroNCAP point performance using test or CAE Simulation results in csv format. Using this tool, NCAP performace for every loadcases can be calculated using X simple steps. This tool can currently takes care of Euro NCAP 7.0 protocol fully and partially the Euro NCAP 5.0 protocol.

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.

Once upon a time there was a pocket calculator called the HP15C. It used a system called Reverse Polish Notation (RPN) for doing its calculations. The Fairwood Calculator is a RPN calculator designed for the computer.

Using statistical modelling against raw data obtained from a USA Annuity mortality table, the Fantastic Life Expectancy Calculator allows users to input a number of parameters to determine their life expectancy. This calculator is provided free and for entertainment purposes only. It does not claim to accurately predict life expectancy for a specific individual or a specific couple.

Fisimula is an extensible calculator/simulator written in c++ which will eventually be able to provide physics functions to other programs

The purpose of this project is to develop a quick and easy points calculator in the style of Weight Watchers' points slide rule. This project is NOT sanctioned by Weight Watchers.

Formol - a simple command-line molar weight calculator that understand the chemical notations.

Calculator with fractions, currently in development

HP-42S Calculator Simulator

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.

The GD Stock Portfolio Calculator is a Google Desktop gadget used to track how much your financial investments are worth.

GNAW is a command-line calculator. It is lightweight but yet powerful. It features advanced arithmetics, user-defined variables and a fully nestable syntax among other things.

I wanted to make a calculator with a memory box which could be freely edited. The value box can also be easily edited. At the moment, it provides basic functions. I hope it can be improved (especially the accuracy-more decimal places)Does conversions too

It basically creates graphical representations for the functions you introduce. Current STABLE branch only includes win32 version. The DEVEL branch includes also a GTK version. Patches are welcome.
