numbat [options] [file]

numbat is a statically typed programming language for scientific computations with first-class support for physical dimensions and units. It functions as both a powerful calculator and a scripting language.
Units can be entered in various formats (km/h, kilometer/hour, GiB, gibibytes, m²) and converted using the -> operator. The standard library includes SI, US Customary, Imperial, Nautical, Astronomical, and Atomic unit systems. Custom units can be defined (e.g., `unit bathtub = 150 L`).
The interactive REPL supports command history, Ctrl-R search, and tab completion.

-e EXPRESSION

Evaluate an expression and print the result.

Physical dimension checking means expressions with incompatible units produce type errors rather than incorrect results.

numbat was created by sharkdp (David Peter) and is written in Rust.
