It is documented --- see under
https://www.postgresql.org/docs/current/datatype-numeric.html
and
https://www.postgresql.org/docs/current/typeconv.html
(particularly example 10.3, which points out that float8 is
considered a preferred type). We are not going to repeat all that
material under every single affected function, if that's what
you're asking for.
