Random number golang

// Uniform Random int (min <= x <= max)
x = rand.Intn(max - min) + min

// Uniform random float (0 <= x <= 1)
x = rand.Float64()  

// Uniform random float (min <= x <= max)
x = (rand.Float64() * (max - min)) + min

Select a random number between 1 and 5 in golang

package main
import (
    "fmt"
    "math/rand"
    "time"    #ADDED
)

func main() {
    // Seed should be set once, better spot is func init()
    rand.Seed(time.Now().UTC().UnixNano())   #ADDED
    fmt.Println(randInt(1, 1000))
}

func randInt(min int, max int) int {
    return min + rand.Intn(max-min)
}
