Since you changed the specifications (an angle can be arbitrary) the client needs to know it too. It's called type contravariance. Example: Client uses int, interface was using int. Interface now uses doubles. - Client get an angle from an object and stores it (incorrectly) in an int. Could be useful. - Client take that angle (which is now truncated) and gives in to another object (which expects a double). Perfectly fine. *However* data was lost in the process. And in C that's a perfectly legal thing to do (some compiler warns, I don't think gcc does) So you have to check clients, too. -- Lorenzo Marcantonio Logos Srl _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
