1. I am told that the Apollo 3500 and 4500 machines support the IEEE floating point standard. Can anyone confirm that and provide more details? 2. If the answer is, "Yes," can anyone tell me how the IEEE capabilities can be accessed from Fortran or C? 3. My specific interest is interval analysis, which uses the directed rounding. Does anyone know of a library of interval arithmetic routines written for the Apollo's? Thanks in advance.

The Apollo DN3000/4000, DN2500/3500/4500, DN560/570/580/590, DN330, and DSP90 all use the Motorola 68881/68882 floating point chips. These chips allegedly conform to the IEEE standard. The functions you want can probably be found in the fpp library (floating point package). See /sys/ins/fpp.ins{.c, .pas, .ftn} and/or The Domain/OS Call Reference Manual (vol 2). -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)
