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, The leftmost bit position is reserved for the sign of the value (positive or negative) and doesn't contribute towards the value of number.

Proper manual logical XOR implementation depends on how closely you want to mimic the general behavior of other logical operators (|| and &&) with your XOR. There are two important things about these operators: 1) they guarantee short-circuit evaluation, 2) they introduce a sequence point, 3) they evaluate their operands only once.

Oct 9, 2010 · Another way of representing the XOR connective is by using a W-like symbol (as in p W q), also used in Set Theory to refer to disjunctive union.

Dec 27, 2010 · In above xor function it will result SIMILAR result as logical xor does not exactly logical xor, means it will result "false for equal values" and "true for different values" with data type matching in consideration.

Feb 11, 2020 · How to insert unusual characters in emacs? offers some suggestions on the pre-existing facilities, incuding using M-x insert-char to search for strings like "xor" and using helm-ucs or helm-unicode to select from a list of Unicode characters. Both of these are a bit more work to select the character than digraphs, though.

Jan 17, 2011 · Best advice is to look up XOR in reference manuals and encyclopedia sites on the net and then write code or script which does the same as the description of what a XOR built-in function does and use your own return or status values. We can not tell you how to do that type of bit compares from within the software community.

Jun 19, 2011 · So, if you XOR a number onto itself, you always get 0 (believe it or not, but that property of XOR has been used by compilers, when a 0 needs to be loaded into a CPU register. It's faster to perform a bit operation than to explicitly push 0 into a register. The compiler will just produce assembly code to XOR a register onto itself).

Apr 30, 2017 · The xor operator on two booleans is logical xor (unlike on ints, where it's bitwise). Which makes sense, since bool is just a subclass of int, but is implemented to only have the values 0 and 1. And logical xor is equivalent to bitwise xor when the domain is restricted to 0 and 1. So the logical_xor function would be implemented like:

Apr 15, 2010 · Hmm.. well I know about XOR (exclusive or) and NAND and NOR. These are logic gates and have their software analogs. Essentially they behave like so: XOR is true only when one of the two arguments is true, but not both. F XOR F = F F XOR T = T T XOR F = T T XOR T = F NAND is true as long as both arguments are not true.

Jan 2, 2010 · It has the behavior such that when you do a xor operation on same bits say 0 XOR 0 / 1 XOR 1 the result is 0. But if any of the bits is different then result is 1. So when you did 5^3 then you can look at these numbers 5, 6 in their binary forms and thus the expression becomes (101) XOR (110) which gives the result (011) whose decimal ...
