intpakX, a Maple package for interval arithmetic created in 1999 by I. Geulig and W. Krämer [1,3], is based on intpak, an experimental Maple package that was created by A.E. Connell and R.M. Corless in 1993 [2]. intpakX contains basic data types and operators for interval arithmetic as well as a variety of numerical methods using intervals. It offers the possibility to compute verified numerical results with a Computer Algebra System and at the same time display the results graphically. With the new version intpakX v1.0, intpakX has been updated and redesigned to work with Maple7. This paper shows the range of features of intpakX and gives some examples of their use.
