In that case, I think our problems are over.  All we have to do is come
up with the decent compiler that Hubert proposes.  I think ADA has all
the facilites needed to do a good job, namely operator overloading and
the ability to specify range and precision of variables.

Ever used a Sun?  Sun's C compiler generates three inline instructions
for abs().  (see /usr/lib/libm.il)
