WebJun 28, 2009 · There are other ways to do this:- if a number is a power of 2, only 1 bit will be set in the binary format. for example 8 is equivalent to 0x1000, substracting 1 from this, we get 0x0111. End operation with the original number (0x1000) gives 0. if that is the case, the number is a power of 2. WebYou can rate examples to help us improve the quality of examples.
