    Tout d'abord, se souvient des cours soulevées exceptions de virgule flottante, puis restaure l'environnement en virgule flottante de l'objet pointé par envp (semblable à std::fesetenv), se pose alors les exceptions en virgule flottante qui ont été enregistrés .
    Original:
    First, remembers the currently raised floating-point exceptions, then restores the floating-point environment from the object pointed to by envp (similar to std::fesetenv), then raises the floating-point exceptions that were saved.
