That looks exactly like what I want because I'd like to use it with maxima.
There are several EXCL references that would need to be changed in
ruan.lisp. I tried to track them down but I didn't want to stray from 754
too far. So the IEEE requirement is to support the interval arithmetic. If
your generic directory is available through maxima, I'm good.
Thanks.
