But your app could be running on a 32 bit only machine, so 64 bit is not a bet to make if you want this program to work on unknown machines. Use -doubleValue to get at least 64 bits, guaranteed.

This is *not* what he wants -- he wants a 64-bit integer.
-longLongValue gives you a 64-bit integer on any platform.  -intValue
gives you a 32-bit integer on any platform, and -integerValue gives
you a native-sized integer on any platform.
The 64-bit transition guide has more information:
