"Decide on one set of names, std::floatN_t, for the type aliases of types with well-known formats."

It was pointed out in the discussions that _FloatN_t in C is subtly
different from _FloatN, so it is unfortunate to use std::floatN_t to
be an alias for _FloatN.

Even if the paper intentionally sticks with the std::floatN_t names,
this point should be highlighted in the prose.

> The paper proposes allowing implementations to provide new extended floating-point types in C++. C already allows such types through the integration of TS18661 into C23. The authors would like to have a discussion around the names of the types and the header where the names are defined, and a discussion of where the behavior of these types differ between languages, including implicit conversions and usual arithmetic conversions. We expect to take preference polls on naming decisions.
