もし値が `parseFloat()` で解析できない場合は、代わりに元の値が使用されます。
もし値が `parseFloat()` で解析できない場合は、代わりに元の（文字列）値が使用されます。特に、入力が空の場合（例えばユーザーが入力フィールドをクリアした後など）、空文字列が返されます。この動作は [DOM プロパティの `valueAsNumber`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement#valueasnumber) とは異なります。

input が `type="number"` を持つ場合は `number` 修飾子が自動で適用されます。
