Calculator is a Windows desktop application that provides standard, scientific, and programmer calculator functionality alongside unit and currency conversion tools.
The tool addresses the need for a capable calculator built into Windows. It handles basic arithmetic with infinite precision so calculations never lose accuracy, supports scientific operations with proper order of operations evaluation, and includes programmer-focused features like base conversion. The application also offers date calculations to find differences between dates or add and subtract time periods, maintains calculation history and memory, and performs currency conversion using live data.
Calculator is suitable for anyone using Windows who needs reliable calculation capabilities beyond basic operations. The scientific mode serves students and professionals requiring advanced mathematical functions, while the programmer mode targets developers working with different number bases. The date calculation feature addresses scheduling and time-span computation tasks. Since this ships pre-installed with Windows, adoption is automatic for Windows users, though the source code is available for those interested in building from source or contributing improvements.
The project maintains an active roadmap documenting planned features and release schedules. The team actively encourages community contributions through documented guidelines and welcomes both GitHub issues and feedback submitted through the Windows Feedback Hub. Development occurs in the open with the source code available for inspection and modification.
