Let's just set it to zero. And either: 1. put a std::cerr warning when a division by zero is detected or 2. remove the check altogether, let it divide by zero and crash. I prefer 2nd option. Much safer. Units have nothing to do with that. -- Janek Kozicki | _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
