mathjs/src/function/bitwise/bitXor.js

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser with support for symbolic computation, comes with a large set of built-in functions and constants, and offers an integrated solution to work with dif

  /**
   * Bitwise XOR two values, `x ^ y`.
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.bitXor(x, y)
   *
   * Examples:
   *
   *    math.bitXor(1, 2)               // returns number 3
   *
   *    math.bitXor([2, 3, 4], 4)       // returns Array [6, 7, 0]
   *
   * See also:
   *
   *    bitAnd, bitNot, bitOr, leftShift, rightArithShift, rightLogShift
   *
   * @param  {number | BigNumber | Array | Matrix} x First value to xor
   * @param  {number | BigNumber | Array | Matrix} y Second value to xor
   * @return {number | BigNumber | Array | Matrix} XOR of `x` and `y`
