unsigned long long
描述
unsigned long long (无号超长整数) 是一个延伸储存空间的变数型别,可以储存 64bits (8 bytes) 大小的整数。不像 long long (有号超长整数),它不储存负数,所以储存范围从 0 到 18,446,744,073,709,551,615 (2^64 1)。
如果无号超长整数要和整数做数学运算,必须在整数常数最后面加上 ULL,强制指定此整数为无号超长整数。
范例
unsigned long long speedOfRobot = 186000000ULL;
语法
unsigned long long var = val;
var
unsigned long long 型态的变数名称
val
指派给变数的值
