If your code is working with CGFloat, then the warning isn't very helpful, because by using CGFloat you've elected to use 32-bit precision. If you want 'double', use 'double'. The warning could be useful on 64-bit compiles to indicate the inadvertent use of 'float' where you meant 'double' or 'CGFloat', but if you're only using CGFloat then that won't happen. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
