推荐答案

十进制.如果您需要担心用于存储数字的内存量，则应该购买一台新计算机. RAM是您最少要担心的问题.

Decimal. If you have to worry about how much memory you have for storing numbers, you should buy a new computer. RAM is the least of your concerns.

是的！正如Christian Graus Decimal所建议的那样，您需要的是数据类型.您可以使用money数据类型(如果使用SQL Server)将其存储在数据库中.

yes!! as suggested by Christian Graus Decimal is the Datatype you need. You can use money datatype(if using SQL Server) for storing it in database.

您可以同时使用double和decimal，但是十进制相对于double而言具有一些优势.

与十进制相比，double可以在更小的内存量中存储很大范围的数字，但舍入误差较小.

decimal值占用更多的内存空间(98位)，但没有任何舍入错误.

You can use double and decimal both, but decimal has some advantages over double.

A double can store a great big range of numbers in a smaller amount of memory compare to decimal but are subject to small rounding errors.

A decimal value takes up more space in memory (98 bits) but does not have any rounding error.
