When an integer literal has no suffix , its type is the first of these types in which its value can be represented 如果一个整数没有后缀，则其类型为以下类型中可表示其值的第一个类型：
Labels may be either valid visual basic 2005 identifierssuch as those that identify programming elementsor integer literals 标签既可以是有效的visual basic 2005标识符（如标识编程元素的标识符） ，也可以是整数。
Plain integer literals that are above the largest representable plain integer ( e . g . , 2147483647 when using 32 - bit arithmetic ) are accepted as if they were long integers instead . 2 . 1 there is no limit for long integer literals apart from what can be stored in available memory 普通十进制整数最大可以为2147483647 (也就是使用32位比特数字的最大值) ,普通的八进制和十六进制数可以4294967295 ,但大于2147483647的数就通过减4294967295变为负数了.长整数的大小是没有限制的,仅仅受制于可用的内存容量
