Function rightArithShift

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)

Parameters

Parameter	Type	Description
x	Number | BigNumber | Boolean | Array | Matrix | null	Value to be shifted
y	Number | BigNumber | Boolean | null	Amount of shifts

Returns

Type	Description
Number | BigNumber | Array | Matrix	x sign-filled shifted right y times

Examples

math.rightArithShift(4, 2);               // returns Number 1

math.rightArithShift([16, -32, 64], 4);   // returns Array [1, -2, 3]
