Numbat is a statically typed programming language designed specifically for scientific computations with first-class support for physical dimensions and units. It combines the rigor of a strongly-typed language with the flexibility needed for real-world scientific work.

Key capabilities include:

Physical dimensions as types: Enforce correctness at compile time with a static type system where dimensions like Length and Time act as types, with optional type annotations and automatic inference
First-class units: Enter units in multiple formats (km/h, kilometer/hour, m², m^2) and convert between compatible units using the -> operator (30 km/h -> mph, 5 in + 2 ft -> cm)
Comprehensive standard library: Includes SI, US Customary, Imperial, Nautical, Astronomical, and Atomic units, plus mathematical and physical constants
Interactive REPL: Features command history, Ctrl-R search, and tab completion for quick one-off calculations
Strict syntax and excellent error messages: Descriptive feedback helps catch mistakes immediately
Modular and customizable: The entire unit system is written in Numbat itself, making it easily extensible with custom units and definitions
Runtime assertions: Verify exact or approximate equality with assert_eq for validation during calculations

Whether you're performing dimensional analysis, unit conversions, or complex scientific calculations, Numbat ensures your results are physically correct while remaining accessible through its intuitive interactive interface.
