[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: iSCSI: Decimal encoding - why 64 bits ?David,
Like many others, I
was under the impression that we had discussed this before. However, I have been
unable to find a discussion in the archive. I think that we may be remembering
the similar discussion on base64 representation for numbers.
The limit of 64 bits
for regular-binary-value appeared with the other value type definitions in
12-90.
The addition was
preceeded by discussion in the Section 4.1 clarifications
thread
but in reading that,
I don't see any discussion of the 64 bit limit for regular-binary values. Then
there was at least one comment in passing about decimal not being natural for
binary strings in the base64 and numerical values thread (see Bill's text
near the bottom of
but whether 64 bits
was the appropriate limit for decimal doesn't seem to have been discussed there
either.
I think this is a
new topic.
Regards,
Pat

it. First of all - if someone will go find the
mail
thread that
discussed this (I also recall a discussion of
numbers vs.
binary items) I'll take a look at it and make a
WG chair
determination of what was or was not concluded.
Kevin's
comment that decimal ought to be limited to 32 bits
is still
valid at this point - a reference to prior discussions
without
specifics isn't enough to dismiss it. My rough
recollection
of the discussion partially matches Julian's -
we reduced
the required size to 64 bits from unlimited on
the
assumption that platforms could cope with this ... and
now
Kevin has raised the issue that two platforms
he
considers
important don't cope well with 64 bit
arithmetic.
I don't
recall discussion of whether to limit to 32 bits vs.
64
bits.
For now,
this issue is open.
Thanks,
