# Bit shift

What is Bit Shift?
Bit shifting is an operation that is performed on all bits of a binary value by moving them either left or right a certain number of places. Bit shifting is used when the operand is used as a series of bits rather than as a whole. In other words, the operand is treated as individual bits that represent something, not a value.

Bit shifting is often used in programming and has at least one variation in every programming language.

Bit shifting can also be known as a bitwise operation.

Bit Shifting, Shift Right and Shift Left differ in two variants and are defined by the number of places at which the shift should take place. For example shifting the operand by one value to the left or shifting the bits 'n' values to the right.

There are also two types of bit shifting, logical and arithmetic. Logical bit shifting can be useful for multiplying or dividing unsigned integers by powers of two. For example, if the value '0001' or '1' is shifted to the left, it will be shifted to '0010' or '2', to the left and back to '0100' or '4'. Shifting to the right has the opposite effect, dividing the value by two per shift. In most cases the displacement is treated as circular. So if you move left, the leftmost value becomes the rightmost value and vice versa.

Logical left shift and arithmetic left shift have the same effect, so Java only uses a single left shift operator (<<) Has. The arithmetic right shift is (>>) while the logic is (>>>). In C and C ++ there is only one shift-right operator (>>); The type of shift to be made is determined by the type of integer being shifted. Signed integers are shifted using arithmetic, while unsigned integers use logical bit shifting. Bit shifting is also widely used in assembly language programming because microcontrollers and microprocessors typically rely on flags represented by individual bits. Since the binary number system is used in assembly language programming, bit shifting is becoming a commonly used operator.
