我正在使用C ++模拟涉及几个（27）刚性常微分方程的生物模型。我的程序在MS C ++ 2010表达式编译器下运行完美，但在g ++编译器（NetBeans 6.8，Ubuntu 10.04 LTS）下失败。问题是某些变量变为NaN。以下是在g ++编译器下程序的每个步骤之后的变量Vm的值：
-59.4 -59.3993 -59.6081 100.081 34.6378 -50392.8 nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan纳米南纳米南纳米南南纳南南南南南南南南南南南南南南
这是MS C ++编译器下相同代码的输出，没有任何变化：

我只使用了“cmath”和“fstream”库。
问题出在哪里？两种情况下的代码完全相同。

Windows和Linux设置了不同的浮点默认值。 ＆LT; fenv.h＆GT;可以通过允许代码抛出而不是默默地帮助你来帮助你调试它。有一些特定于Windows的API可以控制FPU的配置，我认为默认情况下它们不符合IEEE-754标准。
在Windows上，如果您想在IEEE-754标准模式下操作，则需要致电_controlfp。

我怀疑你的代码正在给你一个MS C编译器的答案，但我怀疑它运行得很好。 NaNs（非数字）是计算功能超出其范围的结果。既然你没有提到你是如何解决你的僵硬系统的，我不知道你是否正在记录负数或其他一些松鼠算法，但我确信你在windows代码中进行相同的算术运算。仅仅因为代码试图混淆并不意味着它正在正常运行。
我建议您开始查看两个程序开始分歧的位置，并且在g ++返回NaN的情况下，您可能会发现MS编译器返回0或Inf的可疑操作。
