Title:N2379: SD3#1 (DR 440): FP types being 60559
Reference Documents: N1730
N2323
Summary
SD3 item 1 (DR 440) against C2X: Floating-point types are 60559 (aka 754) formats.
It was decided that DR 440 would be fixed in C2X.
Possible Technical Corrigendum:
In §5.2.4.2.2, insert a new paragraph after paragraph 11:
(追記) Whether a type matches an IEC 60559 format (and perhaps, operations) is characterized by the implementation-defined values of FLT_IS_IEC_60559, DBL_IS_IEC_60559, and LDBL_IS_IEC_60559 (this does not imply conformance to Annex F): (追記ここまで)(追記) 0 type does not match an IEC 60559 format 1 type matches an IEC 60559 format 2 type matches an IEC 60559 format and operations (追記ここまで)
Add to §5.2.4.2.2 paragraph 18 (Example 2)
(追記) FLT_IS_IEC_60559 2 DBL_IS_IEC_60559 2 (追記ここまで)
Existing practice
None known. But, it is easy to add these macros.
