c++ - 我的 C++ 代码在 MS C++ 编译器上运行完美，但在 g++ 编译器上给我 NaN。为什么？

Question

我正在使用 C++ 模拟涉及多个 (27) 刚性常微分方程的生物模型。我的程序在 MS C++ 2010 表达式编译器下完美运行，但在 g++ 编译器(NetBeans 6.8、Ubuntu 10.04 LTS)下运行失败。问题是一些变量变成了 NaN .以下是g++编译器下程序每一步后变量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

下面是相同代码在 MS C++ 编译器下未经任何更改的输出:

-59.4   -59.3993    -59.3986    -59.3979    -59.3972    -59.3966    -59.3959    -59.3952    -59.3946    -59.3939    -59.3933    -59.3926    -59.392 -59.3914    -59.3907    -59.3901    -59.3895    -59.3889    -59.3883    -59.3877    -59.3871    -59.3865    -59.3859    -59.3853    -59.3847    -59.3841    -59.3836    -59.383 -59.3824    -59.3819    -59.3813    -59.3808    -59.3802    -59.3797    -59.3791    -59.3786    -59.3781    -59.3775    -59.377 -

我只使用了“cmath”和“fstream”库。

问题出在哪里？两种场景的代码完全一样。

我怀疑您的代码正在为您的 MS C 编译器提供答案，但我怀疑它能否完美运行。 NaN(非数字)是计算超出其范围的函数的结果。因为你没有提到你是如何解决你的僵硬系统的，我不知道你是在取负数的对数，还是其他一些松鼠算术，但我确信你在你的 Windows 代码中做同样的算术。仅仅因为代码试图蒙混过关并不意味着它正在正确运行。

我建议您开始查看这两个程序从哪里开始出现分歧，您可能会发现一个有问题的操作，即 MS 编译器在 g++ 返回 NaN 的情况下返回 0 或 Inf。
