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. WebFormalizing Java’s Two’s-Complement Integral Type in Isabelle/HOL ETH Technical Report 458 Nicole Rauch and Burkhart Wolﬀ November 16, 2004 Abstract We present a formal model of the Java two’s-complement integral arithmetics. The model directly formalizes the arithmetic operations as given in the Java Language Speciﬁcation (JLS).
