The IEEE 754 rounding mode is a property of the operation rather than of the value(s) involved. To effect this correctly, `/lib/lagoon` implements a `++lake` wrapper in a door-like pattern to modify the core's behavior. This information propagates to gates.

The Lagoon implementation is available in the branch [`sigilante/lagoon-reals`](https://github.com/urbit/urbit/pull/6971).

### Jetting

Jets will resolve at the level of (e.g.) `++add` rather than `++bin-op`.

Lagoon will jet `/lib` into the `non` chapter and place corresponding jets in `/i`.

The Vere implementation is available in the branch [`lagoon-jets`](https://github.com/urbit/vere/pull/638).

### Rationale for `%real`

IEEE 754 `%real`s are a well-understood, well-vetted component in the numerical ecosystem for scientific computing and Urbit's `@r` affordances.

Taken together, these lead us to believe that introducing `%real` to the developer community first is a conservative assay to roll out or try several new features:

1. Jetted `/lib`.
2. Tetchy hardware–software coupling
3. Linear algebra interface and affordances
