In Golang, to convert int to string you can use strconv.Itoa(i) and strconv.FormatInt(i, base). Lets walk through this tutorial to see the examples in practice

Convert int to string with strconv.Itoa(i)

  • You can use strconv.Itoa(i) to convert an integer i to string. Itoa stands for integer to ASCII
package main

import (  
    "fmt"
    "strconv"
)

func main() {  
    i := 1

    s := strconv.Itoa(i)

    fmt.Println(s)
}

Output

1
  • The input parameter must be a 32 bit integer, otherwise you would get the compile error
package main

import (  
    "fmt"
    "strconv"
)

func main() {  
    var i int64 = 1

    s := strconv.Itoa(i) // compile error

    fmt.Println(s)
}

Output

cannot use i (type int64) as type int in argument to strconv.Itoa

Convert int to string with strconv.FormatInt(i, base)

The strconv.FormatInt(i, base) convert the given 64 bit integer i to string in the given base (2 to 36)

Itoa(i) is equivalent to FormatInt(int64(i), 10)

Output

1001
