F* (programming language)
Functional programming language inspired by ML and aimed at program verification From Wikipedia, the free encyclopedia
Remove ads
F* (pronounced F star) is a high-level, multi-paradigm, functional and object-oriented programming language inspired by the languages ML, Caml, and OCaml, and intended for program verification. It is a joint project of Microsoft Research, and the French Institute for Research in Computer Science and Automation (Inria).[1] Its type system includes dependent types, monadic effects, and refinement types. This allows expressing precise specifications for programs, including functional correctness and security properties. The F* type-checker aims to prove that programs meet their specifications using a combination of satisfiability modulo theories (SMT) solving and manual proofs. For execution, programs written in F* can be translated to OCaml, F#, C, WebAssembly (via KaRaMeL tool), or assembly language (via Vale toolchain). Prior F* versions could also be translated to JavaScript.

History
Versions
Until version 2022.03.24, F* was written entirely in a common subset of F* and F# and supported bootstrapping in both OCaml and F#. This was dropped starting in version 2022.04.02.[5][6]
Overview
Operators
F* supports common arithmetic operators such as +, -, *, and /. Also, F* supports relational operators like <, <=, ==, !=, >, and >=.[7]
Data types
Common primitive data types in F* are bool, int, float, char, and unit.[7]
