the `Serialize` and `Deserialize` trait to point the user to the
relevant derives and point out that they might want to check crates

bef110b92a1 changed the display for unexpected floats to always append a
".0" if there was no decimal point found in the formatting of the float.
However, this should only be relevant for finite (i.e., not NaN or inf)
values. The change introduced a test failure in the ordered-float
crate due to this:

The serialization implementation is heavily
inspired by the existing trait implentation for
`std::num::Wrapping<T>`.
The deserializing implementation maps input values
that lie outside of the numerical range of the
output type to the `MIN` or `MAX` value of the
output type, depending on the sign of the input
value. This behaviour follows to the `Saturating`
semantics of the output type.

Debugging a recent cargo-outdated bug, it would have been nice not to
wonder whether a rustc version change in GitHub's runner image was a
contributing factor.
