This project started as a 4 function calculator to impress the grandchildren, since then I have used it as a test bed for any idea that came to mind. Subsequently it now has more bells and whistles than a party hire shop.
I hope that some bits of the code are of help to others starting out.

Updated to correct an error I introduced with the last update. Almost 7 weeks on Play Store with a bug and no feedback. Amazing!

BrownPaper Calculator has been updated on Play Store and the link above to the source code has also been updated.

This new version adds a choice of languages [including Klingon] to the TALK function. These language files can be exported/edited/imported.
Another bell, another whistle.
