分数的可能损失 [英] Possible Loss of Fraction

问题描述

原谅我，如果这是幼稚的问题，但今天我很茫然。

Forgive me if this is a naïve question, however I am at a loss today.

我有一个简单的除法计算，如如下：

I have a simple division calculation such as follows:

double returnValue = (myObject.Value / 10);

值是在对象一个int。

Value is an int in the object.

我得到一个消息，说分数的可能损失。然而，当我换双为int，此消息消失。

I am getting a message that says Possible Loss of Fraction. However, when I change the double to an int, the message goes away.

这是为什么会发生这种事有什么想法？

Any thoughts on why this would happen?

推荐答案

当你把两个int的成浮点值的小数部分丢失。如果你投的项目之一为float，你不会得到这个错误。

When you divide two int's into a floating point value the fraction portion is lost. If you cast one of the items to a float, you won't get this error.

因此​​，例如把10到10.0

So for example turn 10 into a 10.0

double returnValue = (myObject.Value / 10.0);
