What are you doing with the numbers? Do you really need 64 bits of
precision? The double type carries at least 53 bits of precision, so it

doubles are reasonably fast, too.

I think it's the C Language Dialect build setting. Enter "dialect" in the
Build Settings search field. Choose a dialect that has long long.
