func main() {
const abc = 111
fmt.Printf("%t\n", abc)
fmt.Println(math.Pi * abc)
fmt.Printf("%t", math.Pi)
}
result:

func main() {
const abc int = 111
fmt.Printf("%t\n", abc)
fmt.Println(math.Pi * abc)
fmt.Printf("%t", math.Pi)
}
result:
constant 3.14159 truncated to integer
Why when i typed abc int ,the compiler will error.
But,first example tell me on runtime the abc type is int.
this is why?
