The operator works by looking at each bit, and returning 1 if the bit is 1 in either of the inputs. So: 0011 0101 = 0111. If a bit is 0 in one input, then you get the bit from the other input.

WebOct 1, 2010 · What you are asking is essentially not why there are bitshift operators in C#/Java, but why the javac compiler doesn't optimize multiplications and divisions with powers of two into bitshifts. The knee-jerk reaction to this is that multiplication and division have different semantics than bitshifts, so it does not map 100% to replace the ... WebJun 4, 2015 · The inverse of 0 should be 1. 0 is 0b0, and the inverse of that is 0b1. Also, using long bits results in NaN most of the time.
