Flocq

The Flocq library for formalizing floating-point arithmetic in Coq

Keywords: Floating-point - Arithmetic code - Coq

Functional Description: The Flocq library for the Coq proof assistant is a comprehensive formalization of floating-point arithmetic: core definitions, axiomatic and computational rounding operations, high-level properties. It provides a framework for developers to formally verify numerical applications.

Flocq is currently used by the CompCert verified compiler to support floating-point computations.
