![]() Instead of being filled with all 0s, as in logical shift, when shifting to the right, the leftmost bit (usually the sign bit in signed integer representations) is replicated to fill in all the vacant positions (this is a kind of sign extension). 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 number of bit positions, and the vacant bit-positions are filled in. ![]() The two basic types are the arithmetic left shift and the arithmetic right shift. In computer programming, an arithmetic shift is a shift operator, sometimes termed a signed shift (though it is not restricted to signed operands). ![]() Arithmetic shift operators in various programming languages and processorsĪctionScript 3, Java, JavaScript, Python, PHP, Ruby Ĭ, C++, D, C#, Go, Julia, Swift (signed types only) The empty position in the least significant bit is filled with a zero. A left arithmetic shift of a binary number by 1.
