The Uno Calculator is a port of the Windows Calculator to C# and to the Uno Platform for iOS, macOS, Android, WebAssembly and Linux.
The app provides standard, scientific, and programmer calculator functionality, as well as a set of converters between various units of measurement and currencies.
The Uno Calculator will regularly follow with the Windows Calculator updates. You can get it from the App Store, Play Store, in your browser, Snap Store for Linux and of course the original calculator on the Microsoft Store.
- Standard Calculator functionality which offers basic operations and evaluates commands immediately as they are entered.
- Scientific Calculator functionality which offers expanded operations and evaluates commands using order of operations.
- Programmer Calculator functionality which offers common mathematical operations for developers including conversion between common bases.
- Date Calculation functionality which offers the difference between two dates, as well as the ability to add/subtract years, months and/or days to/from a given input date.
- Calculation history and memory capabilities.
- Conversion between many units of measurement.
- Currency conversion based on data retrieved from Bing.
- Infinite precision for basic arithmetic operations (addition, subtraction, multiplication, division) so that calculations never lose precision.
