Am I missing something?

I don't know what the default compile settings are for 64-bit machines,
so I could be wrong. However, I think the default is 32-bit only,
regardless of environment. You have to set the compiler to also compile
64-bit binaries in the Info window of the project (right click on your
project name

Thanks for correcting that. I'd forgotten that long long existed.

This is a test app that I'm using to test a concept (nothing to ever
release), and I came across this oddity.
As for the build settings, it was set for 32 bit architecture. I set
it to 32/64 bit, and also Native Architecture of Build Machine, but
after cleaning and building again, I get

Don't expect, measure. What does sizeof(d) give?
Also, if you want a 64 bit integer, use int64_t. NSInteger changes size
depending, as others have said.

long long matches up with the method names used in Cocoa. I find it
a lot easier to use that rather than int64_t.

Doh! The architecture was still set on i386.
Once I changed it to x86_64, I got the correct log message.
Looks like I still got some learning to do about how Xcode works. =)
Thanks for the help, everyone!

Try this and see if it works any beter:
NSInteger d = [@43253234929732
11 matches
