   * Bitwise OR two values, `x | y`.
   * For matrices, the function is evaluated element wise.
   * For units, the function is evaluated on the lowest print base.
   *
   * Syntax:
   *
   *    math.bitOr(x, y)
   *
   * Examples:
   *
   *    math.bitOr(1, 2);               // returns Number 3
   *
   *    math.bitOr([1, 2, 3], 4);       // returns Array [5, 6, 7]
   *
   * See also:
   *

   *
   * @param  {Number | BigNumber | Boolean | Array | Matrix | null} x First value to or
   * @param  {Number | BigNumber | Boolean | Array | Matrix | null} y Second value to or
   * @return {Number | BigNumber | Array | Matrix} OR of `x` and `y`
