If we do not have intervals available to bound numerical errors, users will not know, when they get different results on different platforms, whether the differences are the result of a bug of some sort, or just numerical instability. At Sun, there has already been an internal effort to add intervals to Java. This effort is mainly promoted by Bill Walster, Sun's leading interval researcher. Help is needed. Ideas are needed.
Support is needed.
However, the language is still, basically, in the design stage. Sun is making a serious effort to accommodate potential users, and it will definitely respond to the customer input. We all know that this is not true but sometimes we believe it anyway. We forget that the numeric answers we get have high precision but perhaps no accuracy. I want the computer to tell me it can get the answer or not.
