Open Source C Calculators for Windows - Page 3

LMP is a command line "calculator" comparable to the GNU command expr, but more flexible. It supports floating point and complex numbers and even higher level operations like differenziation and integration.

MLS6(BG9AMG's the Maidenhead's Locator System Calculator 6th) is a free calculator program, which can convert Maidenhead's Locator System Grid Square into a coordinate(Lat/Lon) and gernerate a GoogleEarth kml file, distri- buted under GPL.

Mole (Chemistry Calculator) can calculate molar mass, number of moles and atoms, empirical and molar formulas and can do stoichiometric calculations such as percent yield and limiting reactant. Mole can also do gas stoichiometry and gas law calculations.

Big Integer Calculator with a simple micro controller (AVR MEGA32). 100 Digits now but soon it will go further long!

Have you ever imagined not having to do math to convert the various number systems and still make arithmetic calculations with different numerical systems in the same expression? That's what makes this application. You can mix decimal, binary, octal and hexadecimal arithmetic operations using the symbols "+, -, *, /,^,". You can put "e" to use Napier's constant, put "pi" to use pi constant and put a "!" in the of numerical system form to factorization. So let's start doing the math in an instant with this application and save the rest of the time for more useful things of interest.

An open source RPN calculator written in C

Pilot logbook flight time calculator, designed to perform quickly additions of your flight hours and minutes. Written for aviation pilots it can be modified for many activities requiring lobook entries

Polishcalc is a simple RPN calculator. It is very small and useful.

Rascal, the Advanced Scientific CALculator, is a platform independent modular calculator. Based on modules for integer, doubles, strings, vectors and matrices it can be easily extended with existing C or C++ code.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

ReactOS Calc is a scientific calculator. It has been written to be a clone of calculators included into MS Win32 operating systems. It has a similar user interface and keyboard shortcuts. It will be released under GNU GPL license.

SDCal is a fast sudoku-calculator. SDCal Pro provides a gtk+ interface for SDCal. Now SDCal will support editing sudoku, solving sudoku step-by-step, estimating difficulty and creating nice sudoku problems!

SigmaCalc is a simple parsing calculator that is simple yet powerful. It is created in C and is a handy tool for parsing mathematical expressions from other applications.

Small-K (Small Calculator) is a command line based mathematical expression evaluating engine in C. It supports symbolical extension in the forms of math functions with arbitrary number of arguments (e.g. f(1, 3)) and variables (e.g. PI).

Speichenrechner is an extremely simple, platform independent calculator for bicycle spoke lengths. Speichenrechner ist ein extrem einfaches, plattformunabhängiges Programm zur Berechnung der Länge von Fahrradspeichen.

TI83dk is a set of tools and a library to allow users to cross-compile to the TI-83 graphing calculator using the open source SDCC compiler

Simple Text Based Calculator written in C. Please leave comments or email me suggestions on update. Shell script included in files.

This tool is specifically for people who play the Online Browser-Based Game, "TribalWars" http://www.tribalwars.net. With this tool, a player can calculate the time required to produce the given resource.

A simple program that calculates up to 6 parameters to help you using Timers. It is done to be used with ever single MCU (PIC, ATMEL, Freescale, etc) and plataform (Arduino, Raspberry, Edison, etc). Just enter yours parameters and let the program calculate all the needed values to help you. It also saves a .txt file with results, if you need to see it again later and save your inserted values (no one likes to retipe values everytime, right?) Isn't program translated to your language? Use the e-mail in the program to know how to translate the program to your language. Missing feature? Contact via email too. Want to help me to develop for Mac or Linux? You know the way (:

Transcalc is an analysis and synthesis tool for calculating the electrical and physical properties of different kinds of RF and microwave transmission lines. Transcalc is built using the GIMP toolkit (GTK+) for its GUI interface.

Weight Watchers Point Calculator will allow you to calculate your points from calories, grams of fiber and grams of fat.

mathSuite is a very powerful Mathematical Suite which deals principally with complex algebric and geometric operations. It is powered by the fabulous ExprEval C Parser. The main purpose of this project is fast math-oriented algorithm virtualization, with an optimized direct text interface. Also it gives you a very powerful and fast Calculus Environment which let you handle easily interchangeable variable lists, matrices, LOGS and Settings Layouts with optimized Items Lists Managing Engine. You'll also be able to execute your own scriptfiles with a basic math-oriented beta script language. Some feature regarding Matrices and Linear Algebra Operations are LU-Factorization, SVD Decomposition, Rank Calculator, Ill Condition Checking and more... There are also a very powerful Linear System Solver and Basic PRELoaded Functions Integrator Engine.

Calculates various math constants to arbritary precision using very simple algorithms. Supports three different bases and both integer and floating point limbs. Currently tested only on x86 Windows, though it should compile and run fine on Linux too.
