		(4) 16进制的前缀:	0x || 0X（字母x不区分大小写，即0x与0X等价）

		e.g.
			fmt.Println(strconv.Atoi("08"))  	// 8 <nil>
			fmt.Println(strconv.Atoi("0xg")) 	// 0 strconv.Atoi: parsing "0xg": invalid syntax

			// 0开头是"8进制数"，8进制数不应该出现"8"，所以转换失败
			fmt.Println(cast.ToIntE("08")) 		// 0 unable to cast "08" of type string to int64
			// 0x开头是"16进制数"，16进制数不应该出现"g"，所以转换失败
			fmt.Println(cast.ToIntE("0xg")) 	// 0 unable to cast "0xg" of type string to int64

		e.g.1
		   (nil) 	=> 0 <nil>
		   (false)	=> 0 <nil>
		   (true)	=> 1 <nil>
		   ("")		=> 0 unable to cast "" of type string to int64
