Take a look at +[NSDecimalNumber decimalNumberWithString:] <http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSDecimalNumber_Class/Reference/Reference.html#//apple_ref/doc/uid/20000179-decimalNumberWithString_> Since it is a subclass of NSNumber, it implements unsignedLongLongValue. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
