Which proposal(s) is / are affected?

P0067

Which compiler / toolchain is affected?

Clang

Currently both cppstat and cppref are wrong.

Cppstat incorrectly claims that v7 adds FP support, but v7 adds everything other than FP support.

Also the cppstat notes for v14 and v20 basically say the same thing, which is wrong. (v14 says "add float and double", while v20 says "everything is complete except long double" - same thing).

Also (this is where cppref is wrong), FP to_chars() support seem to have added in v16, not v14 (at least godbolt shows that: https://gcc.godbolt.org/z/jxfGvdTcr).

Also cppstat doesn't mention that long double to_chars falls back to double to_chars, probably a good idea to mention this.
