Calculator is an Android scientific utility app that combines everyday arithmetic with advanced mathematical features. Beyond basic operations, it offers specialized panels for functions, matrices, graphs, and hexadecimal conversions, making it suitable for students, engineers, and professionals.
The app supports matrix operations (determinants, eigenvalues, dot and cross products, transpose, inverse), graph visualization of equations in X and Y variables, and base conversions between decimal, binary, and hexadecimal. Trigonometric functions can be calculated in radians or degrees, while a history feature allows users to review and reuse past calculations.
A custom Advanced Display component manages structured input, enabling seamless editing of complex expressions, matrices, and functions. Clipboard integration (cut, copy, paste) and context menus make expression handling intuitive. The app also supports Multi‑Window, allowing multitasking alongside other apps, and includes a home screen widget for quick calculations.
Together, these modules make Calculator a comprehensive scientific tool, blending everyday usability with professional‑grade features.
