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... http://www.h-schmidt.net/FloatApplet/IEEE754de.html |
