如何通过除以小数来获得准确的值

问题描述

我有这个代码

I have this code

decimal total = 2m;
decimal discount = 0.2m;
decimal disPercent = discount / total;

disPercent值应为0.0909090909090909

但我得到0.1

我该怎么办才能得到0.0909090909090909？





请注意值是例如，我总是从数据库中得到它们作为十进制价值



我的尝试：

disPercent value should be 0.0909090909090909
but I get 0.1
what should I do to get 0.0909090909090909?


note that the values are for example, I always get them from database as decimal values

What I have tried:

decimal total = 2m;
decimal discount = 0.2m;
decimal disPercent = decimal.Divide(discount, total);

无法正常工作

not working

推荐答案

0.2 / 2.0 == 2.0 / 20.0 == 1.0 / 10.0 == 0.1
