WebIn computer programming, an arithmetic shift is a shift operator, sometimes termed a signed shift (though it is not restricted to signed operands). The two basic types are the arithmetic left shift and the arithmetic right shift.For binary numbers it is a bitwise operation that shifts all of the bits of its operand; every bit in the operand is simply moved a given …
