An analogous project written in C# can be found here: https://github.com/swharden/JLJP Liquid junction potential calculator. It's a tool for scientists and engineers who have to do with electrochemistry and electrokinetics. When two solutions containing ions are put into contact, possibly through a porous diaphragm, a voltage develops across them. The calculation of the voltage is not trivial. The program is written in Java. Includes classes that can be included in other programs, together with graphical interfaces (also as an applet).

This software bundle contains: a 2d video game, a random password generator, a unit conversion program, stopwatch/countdown programs, two calculator apps, a cmd slotmachine game, and a cmd texteditor NOTE: I make this software as a hobby, It is by know means professional software.

Here I publish some humble web applications that I have developped.

JustCalc is a scientific calculator Java applet for mobile phones. JustCalc distinguishes itself from other calculators because expressions are typed into an editable text field before being calculated.

This is a calculator project for the JvS text based role playing game. We use VB to run it. This is a windows form application.

KAlgebra is a MathML-based graphic calculator, thought to bring to the user its power by solving expressions written in MathML or calculating converted common equations to MathML. This project now belongs to KDE Edu. http://edu.kde.org

Fire managers and personel have a big responsibility in determining fire conditions on a day to day basis. KBDI (keetch-Byram Drought Index) calculator helps in determining the KBDI on a daily basis. It comes with several features including a database to

KPNClac is a polish notation calculator intended to inspired by the HP48 Series calculators. It handles complex numbers and will someday handle matricies. The next current development version allows user programmable functions via python.

Introducing Kaixax555's Addition Calculator! Calculating 20 whole numbers, decimals and negative numbers at a time!

Kalculate provides a user-friendly calculator for the average desktop user. Its focus is to develop features that make it friendly and usable instead of features that provide advanced mathematics.

Scientific calculator with math syntax that supports user-defined variables and functions, complex numbers, and estimation of derivatives and integrals Features Operators: +, -, *, /, !, % Groups: (), [], ⌈ceil⌉, ⌊floor⌋ Vectors: (x, y, z, ...) Matrices: [x, y, z; a, b, c; ...] Pre-defined functions and constants User-defined functions and variables Root finding using Newton's method (eg. x^2 = 64). Note: estimation and limited to one root Derivation (prime notation) and integration (eg. integral(a, b, x dx) The value of an integral is estimated using Simpson's 3/8 rule, while derivatives are estimated using the symmetric difference quotinent (and derivatives of higher order can be a bit inaccurate as of now) Complex numbers Understands fairly ambiguous syntax (eg. 2sinx + 2xy) Syntax highlighting Piecewise functions: , pressing enter before typing the final "}" will make a new line without submitting. Semicolons are only needed when writing everything on the same linef

A simple calculator written in Python and uses Tkinter for GUI.

A small calculator for pilots who need to calculate the volume (or the mass) of a given mass (or volume) of kerozen.

Kontinuum is a calculator program that enables the user to calculate all probabilistic aspects of the Kontinuum RPG system, especially the dice rules.

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.

Load a folder with images from raster electron microscope, choose necessary options and let the algorythm calculate the characteristics of the line.

Many of us use LM555 timer chips to generate clocks, tones for model trains, and all sort of other uses. Calculating the values of the resistors and capacitor in the timing chain, along with the duty cycle for astable operation is a bit tedious on a calculator so I built this small forms based tool to make it easier. It even has the graphic of the chip and the pin numbers to make it easy to hook things up.

LOC Calculator is a simple tool for getting Lines Of Code count for J2EE projects.

This calculates a matrix of monthly loan payments based on the initial principal, seed interest rate, and type of loan. Clicking on a loan amount in the matrix will produce an amortization table with totals. I asked AI to convert my server side perl script into Java script and this is what it produced - with a few extra modifications. Enjoy!

A calculator for use at Louisville Presbyterian Theological Seminary (LPTS), where students often receive scholarships to the bookstore where textbooks are more expensive. This application will tell students where to buy books for the cheapest price.

A GUI based LUA environment for performing mathematical calculations. Comes with a syntax highlighting script editor and has support for plotting graphs. This project's GUI has been contributed from my commercial software, Viipe Keyboard Overdrive.
