在Go中将int和long转换为字符串

I have concurrent routine like this,

Routine 1()
{
for 30 times
Send string
}

Routine 2 (out <-chan string)
{
for
case str := <- out:
        fmt.Println(str)
}

Now, I want to send from routine 1 string like, string + int + string + system time in nanosecond. Can anybody help me how can I achieve this.

Sorry, I asked it too early. It is possible like this:

out <- string + strconv.Itoa(int) + string + strconv.Itoa64(time.Nanoseconds())

Thanks.

Update (Go1): strconv.Itoa64 has been replaced by strconv.FormatInt.
