1. What is Bit Shifting?

Bit shifting is an operation that moves the bits of a binary number to the left or right. It's a fundamental operation in computer programming and digital systems.

2. How Does Bit Shifting Work?

The calculator uses the following equations:

\[ \text{Left Shift: shifted} = \text{value} \times 2^{\text{shift}} \] \[ \text{Right Shift: shifted} = \text{value} \div 2^{\text{shift}} \]

Where:

\( \text{value} \) — The integer to be shifted
\( \text{shift} \) — Number of bits to shift

Explanation: Each left shift multiplies the value by 2, while each right shift divides the value by 2 (integer division).

3. Applications of Bit Shifting

Details: Bit shifting is used in low-level programming, graphics processing, cryptography, and optimizing mathematical operations (especially multiplication/division by powers of 2).

4. Using the Calculator

Tips: Enter an integer value and the number of bits to shift. Select shift direction (left multiplies, right divides). Results are in integer format.

5. Frequently Asked Questions (FAQ)

Q1: What happens when bits are shifted beyond the width?
A: Bits shifted beyond the number's width are discarded. For unsigned numbers, zeros are shifted in.

Q2: Is bit shifting the same as multiplication/division?
A: Only for powers of 2. For other numbers, bit shifting alone isn't equivalent.

Q3: What's the difference between logical and arithmetic shift?
A: Arithmetic right shift preserves the sign bit, while logical shift always shifts in zeros.

Q4: Are there limitations to bit shifting?
A: Yes, shifting beyond the bit width of the data type can lead to undefined behavior in some languages.

Q5: Why use bit shifting instead of multiplication?
A: Bit shifting is often faster in low-level operations and requires fewer CPU cycles.
