Mar 6, 2021 · The XOR ( ^ ) is an logical operator that will return 1 when the bits are different and 0 elsewhere. A negative number is stored in binary as two's complement. In 2's complement, …

XOR evaluation, as you understand, cannot be short-circuited since the result always depends on both operands. So 1 is out of question. But what about 2? If you don't care about 2, then with …

Jan 17, 2011 · How do you do the XOR bitwise operation if you only have available the AND and the OR operations?

Jun 19, 2011 · The compiler will just produce assembly code to XOR a register onto itself). Now, if X XOR X is 0, and XOR is associative, and you need to find out what number hasn't repeated …

Jul 15, 2013 · 2 one is exclusive or -> xor, and the other is or which means at least one of the conditions are met in a truth table. Or is not mutually exclusive, xor is.

Dec 27, 2010 · But a "logical" xor operator (^^) would always have to evaluate both operands. This makes it different to the other "logical" operators which evaluate the second operand only …

I am having some trouble identifying when to use the XOR operator when doing bitwise manipulations. Bitwise And and Or are pretty straight forward. When you want to mask bits, …

Apr 15, 2010 · XOR behaves like Austin explained, as an exclusive OR, either A or B but not both and neither yields false. There are 16 possible logical operators for two inputs since the truth …

My question uses Java as an example, but I guess it applies to probably all. Is there any practical difference between the XOR operator (^ in Java) and the not-equal-to operator (!= in Java), when

Oct 30, 2008 · I think the xor variable swap sucks on out-of-order execution cores. Each subsequent xor has a read-after-write dependency, and needs to wait for the answer to …
