Abakus is a simple calculator for KDE, based on a concept of Roberto Alsina's. Think of it as bc (the command-line calculator) with a nice GUI. Abakus wasn't the only calculator to be developed due to Roberto's brainstorm. You may also want to try Ariya Hidayat's SpeedCrunch (maintained/improved by Johan Thelin). In fact many of Abakus's user interface niceties were donated from SpeedCrunch.
- Added ability to remove all functions or variables, from their respective list boxes on the right, in the right-click menu.
- Out-of-range numbers which are entered (like 2e300) are automatically converted to NaN
- "," is accepted as a decimal separator for the benefit of European users.
- Abakus displays numbers using the correct decimal separator.
- Long results are shown with the beginning of the answer by default, rather than the end. As a side effect the status text shows up on the left, which I find rather disappointing, perhaps that can be fixed with a little more work.
- Keyboard accessible.
- User-defined functions.
- Includes an RPN mode for old-school calculator users.
- Includes a scrollable history window, which can be hidden for compactness. When the history pane is hidden, results are shown directly in the edit line.
- Previous expressions can be entered using the up and down keys.
- Built-in functions, including a full suite of trigonometric, logarithmic, and exponential functions.
- Fully supports KDE, so it supports KDE features automatically, including some automatic DCOP support.
- The calculator supports using variables (which are saved between different runs).
- Automatic parentheses closing.
- Includes predefined values of pi and the natural exponential base (e).
- The last successful answer is stored in the variable ans.
- Compiled in C++ for fast startup speed.
- Both ^ and ** are supported for exponentiation.
- Exponentiation is (correctly) right-associative. What this means is that 2 ^ 3 ^ 2 returns 512 instead of 64.
- Expressions like 3 + -2 are accepted, instead of requiring a separate sign-inversion symbol like the TI family of calculators.

- This download includes the source code and a build system appropriate for building the program under a KDE installation. To reduce the download size for my server, the normal KDE build system is not used, but instead a SCons-based system called bksys is used. Because of this, you may have trouble building. If you have problems, please let me know using the email address included in the README.
- You don't need flex or bison installed to build the program, as I've included the generated sources with the package.
