Good day!
I looked at what calculators are under the android and I realized that they all ...
HandyCalc gave hope, but the author scored on him, and has not appeared for several months ...
On the desktop, I use maxima for calculations, but I did not risk porting it to android,
used to spin somehow yacas - a very good and easy project.
And here recently I also learned that on the iPhone the craftsmen fastened their faces to it.
http://www.mathdrake.com/yacas/index.htmlSo here. Command version of yacas and linux tools on android HOWTO build instructions.
And here I am attaching the source of the iphone project, because they have on their site in a non-renewable form.
As well as the source code of the updated yacas.
Anyone wanting to do such a good thing?
Moreover, there is an example application.
Here are the source for the console yacas for Android:
http://gitorious.org/android/yacasHere are the sources of the graphic UI for iPhone
yacas_iphone.tar.gz(960.19 KB)
But the assembled version of the console for Android 2.1:

I hope that someone will take it :)
