Keeping the number in unsigned packed form can speed verification
How is x'123F' faster to verify than x'123C'?
Unsigned packed would be x'0123'. It's faster than verifying a binary
value when you're dealing with digits, eliminating at least one conversion.
How does packed format help with Endian conversion? Never having
really worked with little-Endian, it always makes my head hurt.
There are different machine architectures. So x'01234567' could appear
in memory as x'67452301' or 'x23016745' - again the digits can be
identified more readily than from a mangled binary value.
Also:
unsigned hex was a compromise
When you say 'unsigned hex', do you mean x'0123'? or x'007B'? Not
clear to me...
My bad - I meant unsigned packed, but out of habit wrote hex.
