Or you could google Ieee 754
http://www.google.ca/search?hl=en&q=ieee+754+test&btnG=Search&meta=

Or.. if your brain doesn't hurt yet..
http://www.intel.com/technology/itj/q21998/articles/art_3c.htm

And this guy actually gives test software for the Win/x86 platform.

I wonder if there is a java applet on a website would let people know that their cpu is compliant.


Google returns
http://www.artima.com/insidejvm/applets/InnerFloat.html
seems ok.. but I don't know what to click on it.

This one is in German, I think...
