Convert an integer to a byte array

Question

I have a function which receives a []byte but I what I have is an int, what is the best way to go about this conversion?

err = a.Wr

Sorry, this might be a bit late. But I think I found a better implementation on the go docs.

buf := new(bytes.Buffer)
var num uint16 = 1234
err := binary.Write(buf, binary.LittleEndian, num)
if err != nil {
    fmt.Println("binary.Write failed:", err)
}
fmt.Printf("% x", buf.Bytes())
