用C#进行除法以获得确切的值 [英] Division in C# to get exact value

问题描述

如果我将150除以100，我应该得到1.5.但是当我像下面这样分割时，我得到1.0:

If I divide 150 by 100, I should get 1.5. But I am getting 1.0 when I divided like I did below:

double result = 150 / 100;

有人可以告诉我如何获得1.5吗?

Can anyone tell me how to get 1.5?

推荐答案

尝试:

 double result = (double)150/100;

当您像以前一样进行除法时:

When you are performing the division as before:

double result = 150/100;

除法首先以Int形式完成，然后将其强制转换为double，因此得到1.0，您需要在方程式中有一个double才能将其除为double.

The devision is first done as an Int and then it gets cast as a double hence you get 1.0, you need to have a double in the equation for it to divide as a double.
