P3397R0: Clarify requirements on extended floating point types

2024-11-18 SG6 Minutes

Champion: Hans Boehm

Summary

The existence of value-changing optimizations makes it not obvious what 60559 conforming behavior would actually mean. It seems that we need to tackle the attributes 60559 talks about first. Also we need to consider that users want fast-math-like optimizations for std::float16_t.
