Thanks to people who translate Calculator++ in different languages:\n
Italian - Gabriele Ravanetti\n
Spanish - Jordi Luna\n\n
This application uses next open source libraries:\n
2. Support for differentiation, integration, calculation of sum and product.\n
Examples:\n
∂(cos(t),t)=-sin(t)\n
2∂(tcos(t),t,2)=-4.469\n
Σ(n/n!,n,1,20)=2.7182\n
∫(1/x, x)=ln(x)\n
∫ab(x, x, 0, 10)=50.0

3. Fixed √ simplification problem\n
4. Performance improvements in functions\' plotting
2. Extended history: save, remove, copy, use from history screen (use long click for additional actions)\n
3. Added Spanish language\n
4. Full numeral base support (dec, hex, oct, bin)\n
5. !!!: Fix for multiplication sign on some devices - if you have strange symbols instead of × - go to the settings and change multiplication sign to *\n
Sorry to inform you but this version of application brings built-in ads.\n
I haven\'t seen in android.market calculator with similar capabilities and I don\'t think I will see it in the close future.\n
But still I want to extend it\'s functionality and support already implemented. The thing is that I cannot do it anymore for free - it takes to much of my time and great efforts from me as
application has become rather big and complex.\n
If you want to support the project and get rid of the ads please purchase special option from application preferences,\n
if you don\'t want to pay or can\'t do it - you still can thank the author of this program by email: se.solovyev@gmail.com, rate application with high mark in android.market\n
or help to translate the application to your native language.
