如果您的C ++标准库实现支持TR1函数
fetestexcept ， feraiseexcept 和 feclearexcept 我还没有这样我无法测试这个），你可以检测到五种浮点错误，然后你可以抛出任何你想要的异常。

If your C++ standard library implementation supports the TR1 functions fetestexcept, feraiseexcept and feclearexcept (mine doesn't yet so I can't test this) you can detect five kinds of floating point errors and then you can throw whatever exceptions you want.

请参阅这里，以了解这些功能的描述。

See here for a description of these functions.

我还推荐Pete Becker（ISBN-13：9780321412997）的书籍C ++标准库扩展：教程和参考一书的第12.3节管理浮点环境一个exc使用示例代码对这些功能的描述。

I also recommend section 12.3, "Managing the Floating Point Environment," of the book The C++ Standard Library Extensions: A Tutorial and Reference by Pete Becker, ISBN-13: 9780321412997, for an excellent description of these functions with sample code.
