The `math/big` package in Go provides arithmetic operations on large integers. One of the types it defines is `big.Int`, which represents an arbitrary-precision signed integer.

`SetInt64` is a method of the `big.Int` type that sets the value of the integer to a given 64-bit signed integer. Here are some examples:

**Example 1:**

In this example, we create a new `big.Int` variable `n`, and set its value to the 64-bit signed integer `123456789` using the `SetInt64` method. We then print out the value of `n` using the `String` method.

**Example 2:**

`SetInt64` is a method of the `big.Int` type that sets the value of the integer to a given 64-bit signed integer. Here are some examples:

package main import ( "fmt" "math/big" ) func main() { var n big.Int n.SetInt64(123456789) fmt.Println(n.String()) // Output: 123456789 }

In this example, we create a new `big.Int` variable `n`, and set its value to the 64-bit signed integer `123456789` using the `SetInt64` method. We then print out the value of `n` using the `String` method.

package main import ( "fmt" "math/big" ) func main() { var a, b, c big.Int a.SetInt64(100) b.SetInt64(200) c.Add(&a, &b) fmt.Println(c.String()) // Output: 300 }In this example, we create three `big.Int` variables `a`, `b`, and `c`. We set the values of `a` and `b` to `100` and `200` using `SetInt64`, respectively. We then add `a` and `b` together using the `Add` method, and store the result in `c`. We print out the value of `c` using the `String` method. The package library for `math/big` is the standard library for arbitrary-precision arithmetic in Go.
