The goal of this project was to provide tools to support the verification and validation process of programs with floating- point numbers. We did investigate two directions: structural testing of a program with floating-point numbers and verification of the confor- mity of a program handling floating-point numbers, with its specification. Practically, a constraint solver over the floats was developed for the gen- eration of test sets in structural testing framework. Different techniques have been developed to evaluate the distance between the semantics of a program over the real numbers and its semantics over the floating-point numbers %U http://pop-art.inrialpes.fr/people/bjeannet/publications/cstva06.pdf %D 2006
