Some Formal Tools for Computer Arithmetic: Flocq and Gappa
2021 IEEE 28th Symposium on Computer Arithmetic (ARITH)(2021)
摘要
This invited paper presents two tools developed by the authors. Their purpose is to help the user in writing proofs regarding computer arithmetic, e.g., certifying a bound on a round-off error, while aiming at a high level of guarantee. Flocq is a library of mathematical definitions and theorems for the Coq proof assistant; Gappa is meant to compute bounds of values and errors, while producing the...
