>>: Right shift
The general forms for these operators are shown here:
value < num-bits
value > num-bits
A 'left shift' shift all bits to the left and a zero bit to be brought in on the right.
A 'right shift' causes all bits to be shifted right one position.
In the case of a right shift on an unsigned value, a zero is brought in on the left.
In the case of a right shift on a signed value, the sign bit is preserved.
