I found half of what I want in com.dovetail.jzos.ByteUtil.unpackLong(). Now
I just need a longPacked() method.

and I am much impressed. I hope the two single machine instructions
o PKU, PacK Unicode, and
o UNPKU, UnPacK Unicode,
figured at least implicitly in this horrendous effort.
As I noted earlierJava does much of its arithmetic in BFP, some of under
the
covers; and the notion of converting PD values into BFP for use in C/C++ or
Java environments, while it can certainly be characterized, even
stigmatized, as a standard practice, is also a good one, the best one at
least until ASCII DFP becomes available on z/Architecture machines.

I suggest writing a new class that has one or more factory
methods for creating a BigDecimal from an array of byte. Don't
extend BigDecimal.
2 cents worth. your mileage may vary.
