## About standard types

| Page | What it covers |
|---|---|
| [How standard types are named, and what is left out](/docs/the-standard-types.md) | A standard type's name says exactly what it is, and a type you might look for may be part of another or left for your app to define. |
| [What every standard type can do](/docs/every-standard-type-meets-one-contract.md) | Every standard type comes with the same baseline of operations, so once you know how one type is built, read, sent, stored and shown, you know them all. |
| [How a standard value is sent, stored and shown](/docs/every-boundary-through-the-contract.md) | A standard value keeps its currency, unit and precision wherever it goes into or out of your program. |
| [Packages use the standard types](/docs/packages-use-the-standard-types.md) | When you declare a type with the same shape as a standard type, the compiler reports the error `type.standard_exists` and points you at the standard type. |
| [Changing a standard type's encoding](/docs/standard-type-encodings.md) | Upgrading Jadpo never makes your stored data unreadable. |
| [A release that adds a standard type](/docs/standard-type-clashes.md) | When a Jadpo upgrade adds a standard type with a name your app already uses for a type of its own, your app never breaks silently. |
