SpeedCrunch is a fast, high precision and powerful desktop calculator.

SpeedCrunch is easy to use. You just type the expression that you want to calculate and press Enter. You can see clearly what you typed along with the result in the scrollable display. That is faster and more convenient, isn't it? You can also paste the expression from the clipboard, that you copied from somewhere else. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R. Before you finish, SpeedCrunch may even give already the answer (calc-as-you-type) Features * history and results on a scrollable display * up to 50 decimal precisions * unlimited variable storage * intelligent automatic completion * fully usable from the keyboard * more than 50 built-in math functions * optional virtual keypad to be used with a mouse * on-the-fly and selection calculation * customizable appearance * syntax highlighting and parentheses matching

HP look-alike RPN calculator based on the Free42 project for Nokia N900

mobile computer. This package contains realistic looking vertical and horizontal skins.

The most famous graph drawing program in the world.

Package for making 2D and 3D graphs from data and functions. Supports lots of output formats, including drivers for many printers, (La)TeX, (x)fig, Postscript, and so on. The X11-output is packaged in gnuplot-x11.

Data files and self-defined functions can be manipulated by internal C-like language. Can perform smoothing, spline-fitting, or nonlinear fits. Can work with complex numbers.

This package is for transition and to install a full-featured gnuplot supporting the X11-output. If you want to skip the X-windows-dependency (e.g. if you're running a small server) just install "gnuplot-nox" and skip this meta-package.
