Detailed Description

Returns its first operands bits shifted right by the amount of the 2nd operand.

The leftmost bit (usually the sign bit) stays the same (sign extension). The right input (shift amount) must be an unsigned integer value. If the result mode has modulo_shift!=0, then the effective shift amount is the right input modulo this modulo_shift amount.
