Does 754-2018 need to state "754-2018 supersedes earlier 754 and 854 revisions" or the like?

Bob Corbett has been studying Fortran's mapping of 754-2008 comparison.

BRANCH CUTS 167 The IEEE standards 754 and p854 take a different approach.

C should spell out the rootn cases in analogous form to 754 to avoid errors.

Response: In 754 (unlike 1788) (signed) zero and (affine signed) infinity are exact and well defined.

The exponent returned by the TS 18661-2 llquantexpdN functions can be computed with 754 operations as logb(quantum(x)).

When IEEE 754-2008 introduced decimal formats (DFP), NaNs were specified in complete detail, with the payload defined to be an integer with p-1 digits for a format of precision p.

Would adding a short float extended format to 754-2018 help?

There is therefore a | need to define the octet-encoding that maps the conceptual Level 4 bit | string encodings of floating-point datums (as specified by IEEE Std | 754-2008) and of decorations (not specified in IEEE Std 754-2008) into | an octet sequence.

Result: It will be http://grouper.ieee.org/groups/msc/754 Currently that site links to 754r.ucbtest.org.

Thomas: I don't see anything in part 3 that would prohibit the functions (encodefN, etc.) from using any NaN encoding allowed by IEEE 754.

Probably more people learn about 754 from wikipedia and textbooks than from a very expensive copy of the standard.

However, in several instances this word is used as an adjective where it is not always clear if the intent is to specify what is included in the 754 standard or to mean common or usual.

After some discussion we decided to leave the 754 definition of pow alone, implying no change in the corresponding C definition.
