The go math.big Int Bit package is a part of the standard Go library used for working with large numbers.

The Bit package provides simple and efficient functions for performing bit-level operations like bit shifting, clearing, or setting. This package is utilized to manage, manipulate, and process large numbers of variable size with ease.

**Example 1:** Implementing the int.Bit function

This method returns the i-th bit of the given integer. So, basically, it takes an integer and an index and returns the corresponding bit.

Output:

**Example 2:** Implementing the int.SetBit function

This function sets the i-th bit of the given integer to the provided value. It takes three parameters, an integer, an index, and the value to set.

Output:

package main import ( "fmt" "math/big" ) func main() { num := big.NewInt(255) // Returns the 3rd bit of the integer bit := num.Bit(3) fmt.Printf("Bit at position 3 in %v is %v\n", num, bit) }

Output:

Bit at position 3 in 255 is 1

This function sets the i-th bit of the given integer to the provided value. It takes three parameters, an integer, an index, and the value to set.

package main import ( "fmt" "math/big" ) func main() { num := big.NewInt(15) fmt.Printf("Original: %v\n", num) // Set the 2nd bit to 1 num.SetBit(num, 2, 1) fmt.Printf("After setting 2nd bit to 1: %v\n", num) }

Output:

Original: 15 After setting 2nd bit to 1: 11This package library is a part of the Go standard library.
