A BRIEF DESCRIPTION OF THE PROGRAM |
|
|
Expression is a freeware, open-source, scientific graphing calculator written in Visual Basic 6.0. It can parse and evaluate numeric expressions (lines of text), plot functions (of x), store to (and recall from) variables, automatically recalculate and display expressions (watch expressions) and convert and display numbers in decimal, hexadecimal, octal and binary formats. Expressions are saved to the Entry History List further editing, and can be entered with the keyboard or mouse--thus combining the ease of use of a push-button graphical user interface (like most other programs) and a console-based (keyboard-centered) interface. This program is very customizable and easy to use. It was designed to be small with the ability to "stay on top", resize dynamically, and be minimized to the system tray. Many common and useful mathematical functions and operators are supported. Perhaps best of all, the source code can be downloaded for your own use and modification. Never use the Windows calculator again! |

THE SOURCE CODE |
|
For those of you who want to modify or customize this program for your own purposes, or even if you're just curious about how a calculator program such as Expression might work, you can download the full source code. Source code can be downloaded, modified, distributed and used freely as agreed to under the terms of the GNU Freeware License Agreement, which is included in the installation zip file. This program was written and compiled entirely in Visual Basic 6.0 beginning with version 1.0.60. Prior versions were written and compiled in Visual Basic 5.0. Please note that plans are currently under way to port the program to the Visual Studio.NET environment. |
