大数？

2 ^ 64是18446744073709551616 差别很大...... 迈克尔。 .... forgot to mention that most systems now use 64 bits for date/time... and if you are thinking I was wrong that 2^32 is 2147483648, integer issigned - in otherwords it is 2^31 and the 32nd bit is for +/-. 2^32 is 4294967296 2^64 is 18446744073709551616 Big difference... Michael. 我认为你在这里弄错了。 补充符号，如第一个（2 ^ 32）/ 2代表一个正整数 和最后一个（2 ^ 32）/ 2表示负整数。 - Tim Van Wassenhove < http://home.mysth.be/~timvw> I think you are mistaken here.Complement notation, as in the first (2^32)/2 represent a positive integerand the last (2^32)/2 represent a negative integer. --Tim Van Wassenhove <http://home.mysth.be/~timvw> 这篇关于大数？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
