Golang : Convert(cast) int64 to string

Problem :

You want to convert(cast) a big integer value to string for display.

Solution :

Use strconv.FormatInt() function to convert the int64 value to string. For example :

 package main

 import (
 "fmt"
 "strconv"
 )

 func main() {

 var val int64 = 123456789

 str := strconv.FormatInt(val, 10) // use base 10 for sanity purpose

 fmt.Println(str) // int64 converted to string!

 fmt.Printf("After conversion : %v \n", val) // alternate method works too!

 }

Output :

123456789

After conversion : 123456789
