What's wrong with this division?

如果除2 / 3，它将返回0.66666666666666667.取而代之的是，我使用双值类型的0.0和十进制的0.

If you divide 2 / 3, it should return 0.66666666666666667. Instead, I get 0.0 in double value type and 0 in decimal.

我的目的是除以偶数(例如2 / 3)，并始终将其舍入到1.

My purpose is to divide even (e.g. 2 / 3) and round to 1 always to the nearest.

有帮助吗?

推荐答案

从声音上看，您正在做整数除法.试试这个:

You're doing integer division, from the sounds of it. Try this:

decimal result = 2.0 / 3.0;

对于所有操作，甚至将其强制为小数:

Or even force it to decimals for all of the operations:

decimal result = 2.0m / 3.0m;

这应该给您带来更像您期望的结果.

This should give you a result more like you expect.
