Golang : Convert(cast) bigint to string

Problem :

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

Solution :

Use big.Int.String() function to convert the big integer value to string. For example :

 package main

 import (
 "fmt"
 "math/big"
 )

 func main() {
 bigInt := big.NewInt(123456789)
 bigStr := bigInt.String()

 fmt.Println(bigStr)
 }
