units, or is the rounding behavior programmable?
-*) For this particular calcuation, the LSB behavior is not significant.

However, for some iterative calculations, the LSB behavior may be
significant. It would be useful to understand why the two Crays give
differing results. I can live with a difference, as long as I know
