Val: An Arbitrary-Precision Calculator Language

Val is a simple arbitrary-precision calculator language built on top of chumsky and ariadne. It runs on Linux, MacOS, BSDs, and Windows. Installation is easy via Cargo, or pre-built binaries are available. Val features a command-line interface and REPL with syntax highlighting, persistent history, and emacs-style editing. The language supports functions, loops, conditionals, and a rich set of built-in functions covering arithmetic, logical, comparison, and collection operations. Data types include numbers, booleans, strings, and lists.
