Graphing, matrices, base conversion, and more are at yourfinger tips, and only when you need them.Calculator also has a widget, a floating calculator, and 7 (andcounting) alternative themes. It also runs on Google Glass.History:Calculator was started in June 2012, by Will (myself) and Sean, asdeveloper and designer respectfully. Over 4 months, we added basicsupport for matrices, graphing, and history, and in October 2012,Calculator became officially included within CyanogenMod (and mostcustom ROMs soon thereafter). In January 2013, Nick joined theendeavor, redesigning the graph page, hex page, and has, morerecently, created all of the available themes. In September 2013,Rudy joined for a short time and greatly improved the matrix logic,adding support for functions, order of operations, and more. And,of course, the vast language support has all been thanks to users.The calculator has been, since its start, open source, and isalways looking for more helping hands.Advice:Because the app is intended as a full replacement, it's recommendedthat you disable your default calculator. Go into Settings, Apps,and you will be able to disable it where you would normally findUninstall (Requires Android 4.1+).The source code can be downloaded here: https://github.com/Xlythe/android_packages_apps_Calculator/tree/ics
