Book is out!

Guillaume Melquiond and I published a book that provides a comprehensive view of how to formally specify and verify tricky floating-point algorithms with the Coq proof assistant. It describes the Flocq formalization of floating-point arithmetic and some methods to automate theorem proofs. It then presents the specification and verification of various algorithms, from error-free transformations to a numerical scheme for a partial differential equation. The examples cover not only mathematical algorithms but also C programs as well as issues related to compilation. Buy it here or here.

Who am I?

I am an Inria research director (Directrice de recherche) in Orsay, France, in the Toccata project.

I work at the Inria Saclay - Île-de-France research unit and in the VALS team of the Laboratoire de Recherche en Informatique (CNRS and Université Paris-Sud).
