在寻找为什么我的程序中的double averagePrice是NaN的时候,我偶然发现了Visual Studio代码编译器的这种奇怪行为。编译器显示averagePrice = 0,而double.IsNaN是true,GODOT.GD.Print(averagePrice)打印NaN。
if (double.IsNaN(averagePrice))
{
Godot.GD.Print(averagePrice);
}
字符串
我在Visual Studio中作为控制台应用程序检查了我的代码以进行验证,但Viusal Studio似乎是正确的。我唯一的猜测是Godot扩展导致了这个问题:
Visual Studio Code extensions used
我不确定是否可以提供帮助,但任何关于如何解决这个问题的想法都将不胜感激。谢谢!
Edit:作为参考,由于同一个变量发生了另一个错误,这里是完整的方法:

我还注意到,
double totalTransactionPrice = clearingPrice * quantityTraded;
unitsSold += (int)quantityTraded;
averagePrice += totalTransactionPrice;
型
不更新“averagePrice”值,当我逐行调试时。它在这种情况下保持为零,即使“totalTransactionPrice”不是。当我运行程序而没有预先断点时,它似乎可以很好地计算averagePrice。我不理解。
顺便说一句,很抱歉这里很乱。我没有费心去清理它,因为它现在已经被扔掉了。

原来我是愚蠢的。最初,我在Visual Studio Code的Watchlist中分配了averagePrice,在实验过程中,因为它似乎没有按照我预期的方式工作,所以我做了这件艺术品:
的数据
我已经删除了这个,现在它的行为正常。可能应该是averagePrice == 0到开始。
