This package is meant to give a front end package to Maple's already existing interval arithmetic tools, including the interval object and the command . It over-rides the operations +, -, *, /, ^, and the functions and and the various trigonometric, hyprbolic and their inverse functions and the exponential and logrithmic functions. It solves two problems: the need to call evalr on the result of operations, and it solves the problem of cancelation of equal objects.
