Hi,

I noticed that NSNumber objects with the same value are all have the  
same address.


But since they are created at runtime they must all be held in a big  
container - or am I mistaken?


Thanks in advance

Horst


Only commonly used values are cached (integer with a value < some  
threshold).


Anyway this is an implementation details and you should neither rely  
on this nor have to worry about how the system choose to cached them.
