Валидация также применима к значениям типа `float`.

В этом случае становится важной возможность добавить ограничение <abbr title="greater than"><code>gt</code></abbr>, вместо <abbr title="greater than or equal"><code>ge</code></abbr>, поскольку в таком случае вы можете, например, создать ограничение, чтобы значение было больше `0`, даже если оно меньше `1`.
