推荐答案
根据这个, long
数据类型可以使用64位保存从-9,223,372,036,854,775,808到9,223,372,036,854,775,807的值。它应该能够容纳9,999,999,999。您确定在所有地方都将该值视为 long
吗?
According to this, the long
data type can hold values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, using 64 bits. It should be able to hold 9,999,999,999. Are you sure that you are treating that value as a long
