Replace calculation back-end of Calculator with the GMP library
Short description
The calculation back-end of GNOME Calculator has many limitations and is very old and buggy. In this GSoC I want to replace it completely with the GMP library, which has many benefits: A lot of calculation bugs get fixed, it allows arbitrary precision arithmetic (no 9 digit limit anymore!), and the calculations are faster. This also makes maintaining and contributing to GNOME Calculator easier.
About me
I am Daniel, a student of Computer Science at the University of Bonn, Germany. If you want to contact me feel free to send an email to daniel _ danielrenninghoff _ com. My IRC nick is dnlrn. I've been using GNOME for many years and think it's great that I now have to opportunity to contribute back to GNOME. You can find my blog here.
Schedule
19. May - 1. June |
Create Vala bindings for the GMP library (create a VAPI file) |
2. June - 15. June |
Integrating GMP with Gnome Calculator. Replace parts of the Number class to use GMP. Hopefully to have basic calculations or more working to midtime evaluation. |
16. June - 29. June |
Rewrite the rest of the numbers class to use GMP. In the process break compability with current code in other parts of GNOME Calculator, for example the Serializer. |
30. June - 13. July |
Fix corner cases in other parts of GNOME calculator, for which the new Number class breaks. |
14. July - 27. July |
Improve error reporting, by saving the start and end token in the Number class |
28. July - 10. August |
Test the code, fix bugs and improve the documentation of the new Number class |
11. August - 18. August |
Last minute bugfixes, evaluation ... |
