Open Source C Calculators - Page 5

Just look what I've got up to. A freaking calculator! Well, the story is simple. I just got in my brains that I needed to make something in C. A program just to learn how to work with this programing language. Well... This is it! Just to learn...

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 (:

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

Winix Open-Calc is an experimental project, mainly for the educational use of the developers. It is a command-line based calculator with some extra features, such as the ability to solve algebraic equations and geometric formulas. For Windows and Linux.

Zipdy is a program for calculating the distance between two zip codes and finding all the records in a RDBMS with a zip code with x miles of another zip code. Zipdy was written in C but is also available in PHP and perl.

bcal (Byte CALculator) is a command-line utility for storage conversions and calculations. Storage, hardware and firmware developers work with numerical calculations regularly e.g., storage unit conversions, address calculations etc. If you are one and can't calculate the hex address offset for (512 - 16) MiB immediately, or the value when the 43rd bit of a 64-bit address is set, bcal is for you. Though it started with storage, the scope of bcal isn't limited to the storage domain. Feel free to raise PRs to simplify other domain-specific numerical calculations so it can evolve into an engineer's utility. bcal follows Ubuntu's standard unit conversion and notation policy. Only 64-bit operating systems are supported.

Calctool is the graphical calculator application that was in the OpenWindows Deskset of the Solaris 8 operating system. Sun Microsystems Inc. have kindly given permission to release it. It incorporates a multiple precision arithmetic packages based o

CLIC is a command line interface calculator based on readline library.

Fraction calculator. For now only in text mode, but finally I plane making a GUI for Linux & other platforms. Finally all calculator's code will be accessible for both Linux/Unix architectures.

Gafix is a program, which communicates with a Casio CFX 9850 calculator. The programs can be transfered and received by this program. In addtion the editor converts between cat and raw files to make them read and editable by the user.

ganc is a powerful gnome2 based algebraic calculator. It supports all basic arithmetic operations and functions, definition of variables and handling of numbers in any base. Input can be entered by typing or by using the provided keypad.

GTK based RPN calculator for Linux/Unix. Currently under development, but supports Real Numbers, Complex Numbers, Matrices, and Vectors

We are going to make a multipurpose librairy for the Texas instrument 68k calculator (TI-89 & TI-92+) We are planning to add optimized graphic routine, and a lot more... Grayscale graphic will be added too, of course :)

GRPN is a graphical reverse polish notation (RPN) calculator. GRPN is written in C and uses the GIMP Toolkit (GTK) for the GUI.

gWcalc is a graphics front-end for Kyle Wheeler's excellent Wcalc scientific calculator. It uses the GTK+ toolbox, and adds extensive configuration and session history possibilities.

For developing calculator programs. Digging for fun.

This is calculator pilot project, that is work on iPhone OS 2.2.1. This project is not work properly now. it's working user friendly as soon as possble. This project member are two developer. members skill will be beginner. thanks for your concern.

ISL Equilibrium Calculator,which process solid-liquid equilibrium calculation by using Harvie extended Pitzer's ion interaction electrolyte solution model and particle swarm optimization Gibbs free energy minimization (GEM). ISLEC is an efficient tool for solid-liquid equilibrium calculation, and can simulate the crystallization path of seawater and salt lake brines. ISLEC is suitable for related researches and process design.
