Fwd: Decimal Floating-Point Formats

Subject: Decimal Floating-Point Formats
Reference http://754r.ucbtest.org/proposals/decimal/
As I recall, at the January '03 meeting, we agreed to adopt the format
proposals in the reference, but with one minor modification.
The reference, Table 3, note 1, states that e = 191, 767, and 12287 are
invalid for their respective formats. This is in keeping with the
principle that the reciprocation operation should have maximum opportunity
of success without inducing overflow or underflow.
I believe the subcommittee considered this matter, and determined that
these values of e should nonetheless be considered as valid, and that,
therefore the present note 1 should be deleted. Does anyone else recall
this, or is it a figment of my imagination?
