Calc is a macOS calculator app with arbitrary-precision decimal math, scientific functions, keyboard input, native copy support, and calculation history.

Requirements #

Xcode command line tools available

Scripts #

Command	What it does
`./build.sh`	Build a Release app into `./.build/Release/Calc.app`
`./debug.sh`	Build a Debug app into `./.build/Debug/Calc.app` and open it
`./debug.sh --build-only`	Build the Debug app without launching it
`./debug.sh --exec`	Build the Debug app and run the binary directly in the terminal
`./test.sh`	Run the test suite

Scientific input #

Text input supports sin, cos, tan, asin, acos, atan, ln, log, log10, sqrt, abs, exp, pi, and e.

Basic arithmetic stays exact for large integers and decimal expressions; the display adds grouping separators and switches to scientific notation for very large values.
