즉, `0.5`는 유효한 값입니다. 그러나 `0.0` 또는 `0`은 그렇지 않습니다.

<abbr title="less than"><code>lt</code></abbr> 역시 마찬가지입니다.

## 요약

数值校验同样适用于 `float` 值。

能够声明 <abbr title="大于"><code>gt</code></abbr> 而不仅仅是 <abbr title="大于等于"><code>ge</code></abbr> 在这个前提下变得重要起来。例如，你可以要求一个值必须大于 `0`，即使它小于 `1`。

因此，`0.5` 将是有效值。但是 `0.0`或 `0` 不是。

对于 <abbr title="less than"><code>lt</code></abbr> 也是一样的。

```Python hl_lines="11"
{!../../../docs_src/path_params_numeric_validations/tutorial006.py!}
```

## 总结

, `0.5` 🔜 ☑ 💲. ✋️ `0.0` ⚖️ `0` 🔜 🚫.

&amp; 🎏 <abbr title="less than"><code>lt</code></abbr>.

```Python hl_lines="11"
{!../../../docs_src/path_params_numeric_validations/tutorial006.py!}
```

## 🌃

`0.5` wäre also ein gültiger Wert, aber nicht `0.0` oder `0`.

Das gleiche gilt für <abbr title="less than – kleiner als"><code>lt</code></abbr>.

=== "Python 3.9+"

    ```Python hl_lines="13"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial006_an_py39.py!}
    ```

=== "Python 3.8+"

Assim, `0.5` seria um valor válido. Mas `0.0` ou `0` não seria.

E o mesmo para <abbr title="less than"><code>lt</code></abbr>.

```Python hl_lines="11"
{!../../../docs_src/path_params_numeric_validations/tutorial006.py!}
```

## Recapitulando

Таким образом, `0.5` будет корректным значением. А `0.0` или `0` — нет.

То же самое справедливо и для <abbr title="less than"><code>lt</code></abbr>.

=== "Python 3.9+"

    ```Python hl_lines="13"

## Number validations: floats, greater than and less than

Number validations also work for `float` values.

Here's where it becomes important to be able to declare <abbr title="greater than"><code>gt</code></abbr> and not just <abbr title="greater than or equal"><code>ge</code></abbr>. As with it you can require, for example, that a value must be greater than `0`, even if it is less than `1`.
