golang强制类型转换和类型断言

    public static void main(String[] args){
        int a = 1;
        double b = 1.0;
        System.out.println(a * b);
    }

func Test()  {
 var a int = 1
 var b float32 = 1.0
 fmt.Println(float32(a) * b)
}

type(v)

var a int32  = 10
var b int64 = int64(a)
var c float32 = 12.3
var d float64 =float64(c)

func Test()  {
 var a int =10
 var b *int =&a
 var c *int64 = (*int64)(unsafe.Pointer(b))
 fmt.Println(*c)
}

func Test()  {
 var a interface{} = 10
 _,isInt := a.(int) // 进行类型的断言的变量必须是空接口
 if isInt{
  fmt.Println(a)
 }
}

interface{}.(type)
