Today, I will show you how do I convert int to int64 in golang, as mentioned above I’m going to use the Itint64oa()
method which is provided by the golang.
Let’s start our Golang convert int to int64 example

func main() {
var n int = 97
m := int64(n)
fmt.Println(m)
fmt.Println(reflect.TypeOf(m))
}
