Catching floating exceptions

I am unable to catch floating exceptions (e.g. divide by 0 or 0/0)
using the standard exceptions defined in stdexcept. What is the
recommended way to catch such exceptions?

Thanks,
Song

James, you forgot to mention the gratuitous munting of your signature!

Is it still doing it? I think that that was due to the way I'd
integrated vim into Firefox, and (I hope) I've fixed it (on all
of the machines I use).

Please don't quote signatures or all that google crap.
Don't blame it on Google.
I wasn't, I was whinging about the - Hide quoted text -
nonsense some google uses leave in their replies.
Which is also Google's fault.
Just like about all the spam you find in newsgroups. It's almost
always posted via Google groups, because their disposable accounts
make abuse reports worthless.
That's true, but a different problem. There's no excuse
whatsoever for their news interface to work as poorly as it
does. It's not like they're exactly breaking new ground here.

They do have to make it work within a browser, which is not
designed for this sort of thing.
But that's nothing new. Several of the news services provide web
versions of news readers.

There's no excuse for that - Hide Quoted Text - business. Also no
excuse for not auto-trimming .sigs.

The only real problem I have
with it is that it keeps crashing Firefox.
I haven't had any problem with that, but I haven't used Google to post
much in a couple years.
This is obviously a
bug in Firefox (a program shouldn't crash, no matter what it is
sent), but the problem only occurs when I'll reading news
through Google (and then only when I'm running it with a remote
X server---for various reasons, the only way I can access news
at this site is through Google, using Firefox running on a Linux
box, addressing an X server on a Sparc under Solaris).
Oh.

Thanks to all of you who proposed using setjmp and longjmp, in
conjunction with SIGFPE for handling floating exceptions. It was a
little more involved than I thought due to getting into an infinite
loop, with the signal handler being called endlessly called once the
SIG_FPE exception occurs. I have posted my implementation to
comp.sources.d.

Unfortunately this solution is not fully platform neutral since it
relies on signals.

I am really waiting to see the day when the C++ standard adopts a
consistent way for handling floating point exceptions.

Instead I'm getting neither. I want to be able to track down the...
