2,048 / 2 = 1,024
1,024 / 2 = 512
512 / 2 = 256
256 / 2 = 128
128 / 2 = 64
64 / 2 = 32
32 / 2 = 16
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2
2 / 2 = 1
This process takes 16 steps, and it's also the case that 65,536 = 216.
But, if we take the square root at each level, we get
√65,536 = 256
√256 = 16

Any idea how to make this work with XCode 5 and ARM64? If I leave architectures as standard, it makes the library with armv7, armvs7 and i386 as expected. If I set architectures to standard including 64bit, then the library only contains "cputype 16777223". I use otool -h ...
