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.
