Converting values to other types - float32, int, string

package main

func main() {
    n := 65
    q := float32(n)
    fmt.Printf("%v %T\n", n, n) //  65 int
    fmt.Printf("%v %T\n", q, q) // 65 float32

    f := 42.23
    p := int(f)
    fmt.Printf("%v %T\n", f, f) // 42.23 float64
    fmt.Printf("%v %T\n", p, p) // 42 int

    ns := string(n)
    fmt.Printf("%v %T\n", ns, ns) // A, string

    ns2 := fmt.Sprintf("%d", n)
    fmt.Printf("%v %T\n", ns2, ns2) // 65, string

    fs := fmt.Sprintf("%f", f)
    fmt.Printf("%v %T\n", fs, fs) // 42.230000, string

    fmt.Println()
    num := 258
    fmt.Printf("%v %T\n", num, num) // 258 int
    num16 := int16(num)
    fmt.Printf("%v %T\n", num16, num16) // 258 int16
    num8 := int8(num)
    fmt.Printf("%v %T\n", num8, num8) // 2 int8 - loss of the high bytes!
