mathjs/src/function/bitwise/bitAnd.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 AND two values, `x & y`.
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.bitAnd(x, y)
   *
   * Examples:
   *
   *    math.bitAnd(53, 131)               // returns number 1
   *
   *    math.bitAnd([1, 12, 31], 42)       // returns Array [0, 8, 10]
   *
   * See also:
   *
   *    bitNot, bitOr, bitXor, leftShift, rightArithShift, rightLogShift
   *
   * @param  {number | BigNumber | Array | Matrix} x First value to and
   * @param  {number | BigNumber | Array | Matrix} y Second value to and
   * @return {number | BigNumber | Array | Matrix} AND of `x` and `y`
