GENIUS 0.7.1

GENIUS 0.7.1 is now available

Genius is one of the oldest GNOME projects, it has been the original GNOME calculator before I got wild ideas about it doing absolutely everything. It is programmable has a powerful language and handles many fun features including matlab like support for matrices. It requires GNOME2 (at least glib2 if you don't want a GUI) and a recent enough gmp library. However you can still use the command line version if you prefer non-gui interface.

There is still a lot of work required to make this all nice, mostly it needs to have the function library improved and verified to be correct and documentation needs to be written (the complete help system is not yet in place). Feel free to help out :)

Here are the news in 0.7.1:

* Run EPS output through ps2epsi if it's there which adds a bitmap preview, even though this bitmap preview is fairly crappy
* Add PNG export for plots
* Remove some parenthesis from output where they are not needed
* SYNTAX: InfiniteSum, InfiniteSum2, InfiniteProduct, InfiniteProduct2, now no longer take the tolerance argument and behaviour is controlled by the SumProductTolerance, SumProductSFS and SumProductNumberOfTries like other limits and they return null when limit can't seem to be found
* Add: NumericalLeftDerivative, NumericalRightDerivative
* Fix the NumericalLimitAtInfinity function and its use and with that fix NDerivative (which is now an alias for NumericalDerivative), IsContinuous, IsDifferentiable, Limit, LeftLimit, RightLimit
* Fix the specfile and custom CFLAGS are added after the default ones (Florin Andrei, me)
* LinePlot and SurfacePlot no longer crash when called without arguments
* Fix EPS/PS export for older gtk
* Fixup compilation of GtkExtra-2 with gcc 3.4
* Bunch of "optimizations" and minor fixes
