## What Is a Binary Bit Right-shifter?

This tool shifts binary numbers to the right side. It moves bits of a binary number by a certain number of positions to the right and adds new bits on the left. There are two types of right bit shift: Logical Shift and Arithmetic Shift. In left-shift these operations are the same but in right-shift they are different. The logical right-shift always adds zeros at the beginning of a number. The arithmetic right-shift copies the most-significant bit (MSB) and adds it to the beginning of a number. The MSB can be either a zero or a one. For both types, you can also choose a shift mode that controls the shift behavior. The unlimited mode simply adds the given number of bits at the leaves the original bits unchanged. For example, if the input number is 11010 and shift-length is 2, then the output is 0011010 in logical shift and 1111010 in arithmetic shift. The self-length mode, also known as the constant-length mode keeps the original length of the input number. It deletes as many bits from the end of the binary as it adds at the start, leaving the total length unchanged. For example, if the input number is, again 11010 and the shift-length is, again 2, then the output is 00110 in logical shift and 11110 in arithmetic shift. The truncate mode shortens the binary numbers from the right side to the specified length (k). For example, if the input number is 11010, the shift width is 2, and cut length k is 4, then the output is 0011 in logical shift and 1111 in arithmetic shift. You can also extend the length of output binary numbers by using signed and unsigned padding. The signed padding will use 1-bits and the unsigned padding will use 0-bits. Additionally, you can decorate the shifted bytes with the binary base prefix or postfix. Something super cool about right-shifting is that shifting a number one position to the right is the same as dividing it by 2. Similarly, right-shift by n is the same as dividing it by 2n. Simple and easy!

### Logical Right Shift

In this example, we operate on six binary numbers using the logical right-shift type and unlimited shift mode. We set the shift width to 3 and as a result, all digits in each number are moved to the right by three positions and empty places at the beginning are filled with zeros. The word "unlimited" here means that you could shift the numbers by 900 positions and it would still work.

0101 1010 1111 10100 11001 11110
0000101 0001010 0001111 00010100 00011001 00011110

### Arithmetic Right Shift

This example applies the arithmetic right shift method to several different six-digit binary numbers. As the shift length is set to 2, it moves the first two bits to the right and fills the empty positions on the left with copies of the most-significant bit (MSB). In the first, second, and fourth numbers, the MSB is equal to one, and in all other numbers, it's equal to zero. It also adds a lowercase binary number indicator "0b" to the output.

111111 111000 000111 110011 001100
0b111111 0b111110 0b000001 0b111100 0b000011

This example also performs an arithmetic shift but uses the truncation mode. In this case, the numbers are first shifted one position to the right, then the most-significant bit is duplicated at the beginning, and then numbers get truncated from the right side to 6 characters. After all this, the numbers are sign-padded to a full byte (8 positions) and the suffix "B" is added.

1010101 0101010 111 00110 011 101110111
11110101B 11001010B 11111111B 11000110B 11110011B 11110111B
