package main

import "fmt"

func main() {
	// 比如int64，我想改成bigint
	type bigint int64
	var a bigint
	a = 10
	fmt.Println(a)
	
	fmt.Printf("%T\n",a)  // main.bigint main包.bigint
	

	/* 	//类型别名不能和他本来的类型相加,报错 invalid operation: a + b (mismatched types bigint and int64)

	c :=a +b
	fmt.Printf("%T\n",c)  // main.bigint main包.bigint
	fmt.Printf("%d\n",c)  // main.bigint main包.bigint  */
