End operation with the original number (0x1000) gives 0. if that is the case, the number is a power of 2. shutting down a macbook pro

(x&(~x+1))^x gives 0 if x has at most 1 bit set and nonzero otherwise, except when ~x is INT_MIN, in which case the result is undefined...You could perhaps split it into multiple parts with bitshifts to avoid this but then I think you'll exceed the operation limit. shutting down a chromebook
