SG6: Define narrowing conversions on rank instead of finite value ranges?
SF 2 F 3 N 1 A 0 SA 0

Make rank of overlapped ranges unordered.
SF 2 F 3 N 1 A 0 SA 0

Make operations on unordered ranks ill-formed.
SF 3 F 3 N 0 A 0 SA 0

Lots of feedback in EWG-I in Kona. Want to see again. LEWGI should see this too.

Cologne 2019-07 LEWGI Minutes

P1467R1 Extended Floating Point Types: Design Review

Champion: Michał Dominiak

Minute Taker: Jayesh Badwaik

Start Overview: 07-16 10:42

Start Review: 11:02

Make sure outputting extended floating point types with iostreams works.

Is a type trait needed for determining floating-point conversion rank? Do we need any new type traits for floating point types in this brave new world?

Put the num_put/num_get ABI breaks on Titus' list of ABI breaks.

I"m noticing the LWG notes didn't get added here.

LWG saw this over 3 sessions and asked for various refinements that were made -- culminating in a vote on 2022-04-01

P1467r9 to be sent to Core for inclusion into C++23 with the small amendment discussed?

@jensmaurer and @jwakely -- did we decide if this is CWG or LWG motion?

@dkolsen-pgi
Copy link

@jensmaurer and @jwakely agreed that this paper would be a CWG motion, since the core changes are more significant than the library changes.

It's on the list of CWG proto-motions:
