As you have previously been informed (see Announcement), Sun has released its beta test version of its Fortran 95 compiler, that has a fast intrinsic interval data type. (A standard function interval evaluation takes 1.8 times the time of a corresponding floating point evaluation, and extended interval arithmetic is built-in for non-stop operation. Also, combined with standard-conforming features of Fortran 95, interval matrix and array operations, etc. are available, as well as derived-type operator overloading with intervals as the base type.)
To discuss interval arithmetic issues users encounter while using this compiler, I have set up a mailing list. Anyone can send questions to this list. To participate in resolving such questions, you may subscribe to the list. To subscribe to the list, send mail to
