Difference between logical shift right and arithmetic right shift

Logical right shift means ignoring the sign bit, shifting to the right by one bit, and filling with zeros on the left.
Arithmetic right shift needs to consider the sign bit, shift right by one, if the sign bit is 1, add 1 to the left; otherwise, add 0.
So arithmetic right shift can also perform signed bit division, right shift, n bits is equal to the nth power of dividing 2
