Ideally, interval computations should be part of mainstream languages. In particular, R. Baker Kearfott and other researchers are currently promoting the idea of including interval computations in the new version of Fortran. Currently, there is a new language called Java that is spreading like wildfire. This language is getting more and more popular with people doing applications, e.g., with chemical engineers, industrial engineers, etc., because with Java, they can not only run their programs, but they can also produce the results in a nice dynamic format directly into the Web page. This language is actively supported by Sun Company, that distributes it for free.
Many researchers believe that it is the language of the future.
Let's add intervals to Java. It seems reasonable to add interval computations to Java. A specific feature of Java that makes interval computations especially important for Java is that Java is a platform-independent language. Running the same program on different platforms with different computer precisions, etc., often leads to different results. 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.
