/**
|
|
* 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 | bigint | Array | Matrix} x Value to be shifted
|
|
* @param {number | BigNumber | bigint} y Amount of shifts
|
|
* @return {number | BigNumber | bigint | Array | Matrix} `x` zero-filled shifted right `y` times
