C++Builder and Delphi Exceptions

Hi,

I am doing a research project in C++Builder 5.0 and
I'm using large numbers.

I have some problems with exception handling.

If I perform some operations that overflow the
capacity of the double data type I usually get an
EOverflow exception.

But, sometimes the variables that stores the results
are filled with some C++Builder constants (such as NAN
or INF) and no exception is thrown. But, if I use
these
variables (filled with NAN or INF) I get an error and
my application stops.

My question is how could I handle all these exception
in a uniform manner? I wrote several test functions
that check whether the variables contain the NAN and
INF constants, but this significantly slows down my
application. So I don't want to use this functions
anymore, but I need some mechanisms for preventing
such situations. 

Please help me.

Thank you,
Mihai
