  /**
   * Bitwise right arithmetic shift of a value x by y number of bits, `x >> y`.
   * For matrices, the function is evaluated element wise.
   * For units, the function is evaluated on the best prefix base.
   *
   * Syntax:
   *
   *    math.rightArithShift(x, y)
   *
   * Examples:
   *
   *    math.rightArithShift(4, 2)               // returns number 1
   *
   *    math.rightArithShift([16, -32, 64], 4)   // returns Array [1, -2, 4]
   *
   * See also:
   *
   *    bitAnd, bitNot, bitOr, bitXor, rightArithShift, rightLogShift
   *
   * @param  {number | BigNumber | Array | Matrix} x Value to be shifted
   * @param  {number | BigNumber} y Amount of shifts
   * @return {number | BigNumber | Array | Matrix} `x` sign-filled shifted right `y` times
