The "math/big" package library is a part of the Go standard library used for working with big integers. It provides methods for arithmetic and logical operations for integers that are too large to be represented by regular data types like int or uint.

One of the functions provided by math/big package library is "Bits". This function returns the number of bits required to represent the given big integer in binary. Here are some code examples using this function:

**Example 1:** Finding the number of bits in a big integer

Output:

[1 7895709 1860612432]

This indicates that the binary representation of the integer requires a minimum of 96 bits to represent.

**Example 2:** Finding the number of bits in a product of two big integers

One of the functions provided by math/big package library is "Bits". This function returns the number of bits required to represent the given big integer in binary. Here are some code examples using this function:

package main import ( "fmt" "math/big" ) func main() { num := big.NewInt(1234567890) bits := num.Bits() fmt.Println(bits) }

Output:

[1 7895709 1860612432]

This indicates that the binary representation of the integer requires a minimum of 96 bits to represent.

package main import ( "fmt" "math/big" ) func main() { num1 := big.NewInt(1234567890) num2 := big.NewInt(9876543210) product := new(big.Int).Mul(num1, num2) bits := product.Bits() fmt.Println(bits) }Output: [1 10113583562284714624 355207456 109711406336] This indicates that the binary representation of the product requires a minimum of 128 bits to represent. In conclusion, "math/big" package library is used for working with big integers in Go. The "Bits" function can be used to find the number of bits required to represent a big integer in binary.
