Overview:

Calculator is focused on extending the traditional 4 function calculator, keeping its simplicity while still adding features used in higher level math. It uses the original Android calculator as a base.

The project was started by me in June 2012 and by October 2012 it was accepted into CyanogenMod. Since then, users of the app have helped greatly in cleaning up the ui, improving the matrix features, and translating the app into all the languages currently available. Without them, this app would be nowhere near as polished as it’s become.

Because the app is intended as a full replacement, it’s recommended that you hide your default calculator by either disabling it (v4.1+) or using a custom launcher. Otherwise, the similar app names may prove confusing.

Calculator has the following features and more:

-Basic arithmetic

-Trigonometry

-Complex numbers

-Graphs for X,Y equations

-Matrices

-Hexadecimal and Binary support

-Widget for lockscreen and launcher

-Floating calculator

-History of previous calculations

-Themeing support

-Google Glass support
