Venn diagram of . Exclusive or, exclusive disjunction, exclusive alternation, logical non-equivalence, or logical inequality is a logical operator whose negation is the logical biconditional.
The binary logical operators returned a Boolean value in early versions of JavaScript, but now they return one of the operands instead. The left–operand is returned, if it can be evaluated as : false , in the case of conjunction : ( a && b ), or true , in the case of disjunction : ( a || b ); otherwise the right–operand is returned.
modal operator for “it is possible that”, (in most modal logics it is defined as “¬ ¬”, “it is not necessarily not”). ∃ x P ( x ) {\displaystyle \Diamond \exists xP(x)} says “it is possible that something has property P {\displaystyle P} ”
XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or ( ↮ {\displaystyle \nleftrightarrow } ) from mathematical logic ; that is, a true output results if one, and only one, of the inputs to the ...
For example where denotes the exclusive disjunction (XOR) operation. [2] This operation is sometimes called modulus 2 addition (or subtraction, which is identical). [3] With this logic, a string of text can be encrypted by applying the bitwise XOR operator to every character using a given key.
In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
XOR (exclusive or) is a logical operator whose negation is the logical biconditional. XOR may also refer to: XOR cipher, an encryption algorithm; XOR gate, a digital logic gate; bitwise XOR, an operator used in computer programming; XOR, a 1987 puzzle video game; XOR, an x200 instruction; Xor DDoS, a Linux Trojan malware
A subproject of WikiProject Logic for the purpose of expanding, and integrating the articles describing the Logical Operators. There are 16 binary logical operators. The concept behind each of them is applied in various disparate fields: (logic, mathematics, grammar, computer science, linguistics). Each of the sixteen has the potential to reach ...
