Supports complex mathematical functions and constants
Replaces selected text with calculation results
Lightweight and integrated into macOS

Use Cases:

Quickly calculating sums or formulas in spreadsheets or documents
Performing math in text editors without leaving the current window

CalcBar – Third-party menu bar calculator; offers more UI but not a system service
