     62    * Bitwise right arithmetic shift of a value x by y number of bits, `x >> y`.
     63    * For matrices, the function is evaluated element wise.
     64    * For units, the function is evaluated on the best prefix base.
     65    *
     66    * Syntax:
     67    *
     68    *    math.rightArithShift(x, y)
     69    *
     70    * Examples:
     71    *
     72    *    math.rightArithShift(4, 2)               // returns number 1
     73    *
     74    *    math.rightArithShift([16, -32, 64], 4)   // returns Array [1, -2, 3]
     75    *
     76    * See also:
     77    *
     78    *    bitAnd, bitNot, bitOr, bitXor, rightArithShift, rightLogShift
     79    *
     80    * @param  {number | BigNumber | Array | Matrix} x Value to be shifted
     81    * @param  {number | BigNumber} y Amount of shifts
     82    * @return {number | BigNumber | Array | Matrix} `x` sign-filled shifted right `y` times
