Detailed Description

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

No special handling for the sign bit is performed (zero 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.
