WebThe Bitwise Complement. The bitwise complement operator, the tilde, ~, flips every bit. A useful way to remember this is that the tilde is sometimes called a twiddle, and the bitwise complement twiddles every bit: if you have a 1, it's a 0, and if you have a 0, it's a 1. 0, of course, is all 0s: 00000000 00000000. 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. truth ignited blogs
