ECalc

ECalc is a calculator plug-in for Eclipse that provides the ability to evaluate mathematical expressions. Note the low version number. At this stage the software should be considered a prototype, although it does work pretty well.

To install, just put the jar from the zip-files in your plugin-directory and restart eclipse. To uninstall, remove the jar-file and the directory .metadata/.plugin/se.fnord.ecalc from your workspace directory/directories.

Features

1. Command-history.
2. Functions (sin, cos, tan, asin, acos, atan, min, max, hypot, sqrt, random, round, ceil, floor).
3. Ability to switch between radians and degrees.
4. The basic operators (+, -, *, /, % (modulus), ^ (power)).
5. Bitwise operators (>>, <<, &, |).
6. Input and output in binary, octal, decimal or hexadecimal.
7. The constants pi and e.
8. Variables.
9. User-defineable functions (eg. 'def f(x) { x*2 }', 'def g(x,y) { x*sin(y) }').
10. Probably some things that I forgot.

Todo

1. Package ECalc as a feature.
2. More built-in functions.
3. Fix annoying parser-bug.
4. Refactor code in general and clean the parser code in particular.
5. Ability to list/manage variables and functions.
6. Some kind of context-menu.
7. Fix the TODOs in the source.
8. Make this page interesting.
9. Fix the bugs you tell me about. :)
10. What else? Let me know!
