## Number validations: greater than and less than or equal { #number-validations-greater-than-and-less-than-or-equal }

The same applies for:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

## 數值驗證：大於或等於 { #number-validations-greater-than-or-equal }

使用 `Query` 和 `Path`（以及你之後會看到的其他類別）可以宣告數值限制。

這裡用 `ge=1`，代表 `item_id` 必須是「大於（`g`reater）或等於（`e`qual）」`1` 的整數。

## 數值驗證：大於與小於或等於 { #number-validations-greater-than-and-less-than-or-equal }

同樣也適用於：

* `gt`：大於（`g`reater `t`han）
* `le`：小於或等於（`l`ess than or `e`qual）

## 숫자 검증: 부동소수, 크거나 및 작거나 { #number-validations-floats-greater-than-and-less-than }

숫자 검증은 `float` 값에도 동작합니다.

여기에서 <abbr title="greater than - 보다 큼"><code>gt</code></abbr>를, <abbr title="greater than or equal - 크거나 같음"><code>ge</code></abbr>뿐만 아니라 선언할 수 있다는 점이 중요해집니다. 예를 들어 값이 `1`보다 작더라도, 반드시 `0`보다 커야 한다고 요구할 수 있습니다.

## 数值校验：大于等于 { #number-validations-greater-than-or-equal }

使用 `Query` 和 `Path`（以及你稍后会看到的其他类）你可以声明数值约束。

在这里，使用 `ge=1` 后，`item_id` 必须是一个整数，值要「`g`reater than or `e`qual」1。

## 数值校验：大于和小于等于 { #number-validations-greater-than-and-less-than-or-equal }

同样适用于：

* `gt`：大于（`g`reater `t`han）
* `le`：小于等于（`l`ess than or `e`qual）

## 数値の検証: 浮動小数点、 大なり小なり { #number-validations-floats-greater-than-and-less-than }

数値のバリデーションは`float`の値に対しても有効です。

ここで重要になってくるのは<abbr title="greater than – より大きい"><code>gt</code></abbr>だけでなく<abbr title="greater than or equal – 以上"><code>ge</code></abbr>も宣言できることです。これと同様に、例えば、値が`1`より小さくても`0`より大きくなければならないことを要求することができます。

したがって、`0.5`は有効な値ですが、`0.0`や`0`はそうではありません。
