请教溢出检测
<P 0pt? 0cm>有一个<FONT face="Times New Roman">C++</FONT>函数（不是<FONT face="Times New Roman">VC</FONT>），里面有很多算法，运行时有可能出现溢出(如分母为零,求绝对值大于1的反三角函数asin等)的情况，我希望溢出时能给出提示，我试过<FONT face="Times New Roman">try-catch(…)</FONT>，但好象不好用，谁能帮我解决这个问题？能做个试验吗?谢谢!</P><P 0pt? 0cm>例如：</P>
<P 0pt? 0cm><FONT face="Times New Roman">function(double a,double b,double c,)</FONT></P>
