Golang : convert rune to integer value



Tags : golang rune integer

Just a short tutorial on how to convert a rune into integer. Converting rune to integer value can be useful for generating checksum to ensure that the message transmitted is not tempered with.

 package main

 import "fmt"

 func main() {

  r1 := rune('你')
  i1 := int(r1)
  fmt.Println(i1)
  fmt.Println(string(i1))

  r2 := rune('好')
  i2 := int(r2)
  fmt.Println(i2)
  fmt.Println(string(i2))

  r3 := rune('吗')
  i3 := int(r3)
  fmt.Println(i3)
  fmt.Println(string(i3))

  // or in a more efficient way
  message := []rune{'你', '好', '吗'}

  fmt.Println(message)

 }
