* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types

Here are some of the additional data types you can use:

* `UUID`:

// it returns false only if there is a conversion failure.
func (v Value) bytesToInt() (int64, bool) {
	bytes, _ := v.ToBytes()
	i, err := strconv.ParseInt(strings.TrimSpace(string(bytes)), 10, 64)
	return i, err == nil
}

// Converts untyped value into float. The bool return implies success
// - it returns false only if there is a conversion failure.
func (v Value) bytesToFloat() (float64, bool) {

```

Again, doing just that declaration, with **FastAPI** you get:

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation

## Special types and validation

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.
