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 [6] . It provides a framework for developers to formally certify numerical applications.

Flocq is currently used by the CompCert certified compiler for its support of floating-point computations.

It is distributed as open source, under a LGPL license, at http://flocq.gforge.inria.fr/ . It was first released in 2010. Current version is 2.4.0 released in Sep. 2014.
