The right shift operator (>>) shifts the first operand the specified number
of bits to the right. Excess bits shifted off to the right are discarded.
Copies of the leftmost bit are shifted in from the left. Since the new
leftmost bit has the same value as the previous leftmost bit, the sign bit
(the leftmost bit) does not change. Hence the name "sign-propagating".Copyright © 2021 Codeinu
