The Interval package for Coq
Participant : Guillaume Melquiond [ contact ] .
The Interval package provides several tactics for helping a Coq user to prove theorems on enclosures of real-valued expressions. The proofs are performed by an interval kernel which relies on a computable formalization of floating-point arithmetic in Coq .
It is distributed as open source, under a LGPL license, at http://www.lri.fr/~melquion/soft/coq-interval/ . Most of the work on this library was done while in the Mathematical Components team (Microsoft Research–INRIA Joint Research Center).
