How Do the `` Operators Shift Bits in Go?

Shifting Bits with << and >> in Go

Understanding the functionality of the bitwise operators '<<' and '>>' is essential for effectively handling bit manipulation tasks in Go.

Bitwise Shift Operators

The '<<' (left shift) operator performs the multiplication of a number by a power of 2. For example, "n << x" shifts the bits of 'n' left by 'x' bits, resulting in a value that is equivalent to "n * (2^x)". In essence, each left shift doubles the value of 'n'.

Conversely, the '>>' (right shift) operator performs division by a power of 2. "y >> z" shifts the bits of 'y' right by 'z' bits, resulting in a value that is equivalent to "y / (2^z)". This operation effectively divides 'y' by 2 for each right shift.

Practical Examples

Let's demonstrate these operators through examples:

• 1 << 5: Shifts 1 left by 5 bits, resulting in (1 * (2^5)) = 32
• 32 >> 5: Shifts 32 right by 5 bits, resulting in (32 / (2^5)) = 1
• 0xFF << 4: Shifts the hexadecimal number 0xFF left by 4 bits, resulting in (0xFF * (2^4)) = 0x0FFF
• 0x800 >> 8: Shifts the hexadecimal number 0x800 right by 8 bits, resulting in (0x800 / (2^8)) = 0x0020
