Halfway cases for binary-to-decimal conversion in IEEE 754-1985

[Vincent Lefevre <vincent@xxxxxxxxxx>]

The IEEE 754-1985 standard (note: 1985, not 2008) does not seem to
specify how halfway cases should be rounded for binary-to-decimal
conversions in the round-to-nearest mode, in the ranges where
correct rounding is required. Indeed Section 5.6 (Binary <-> Decimal
Conversion) refers to Section 4 (Rounding), but the rounding of
halfway cases in round-to-nearest is specified only for a radix-2
target format.

So, does an implementation that rounds halfway cases away from zero
for binary-to-decimal conversions can be regarded as an IEEE 754-1985
comforming implementation (if everything else is OK)?

Or is this lack of specification regarded as a defect corrected by
IEEE 754-2008?
