/**
 * `` is an input field web component that only accepts numeric input.
 *
 * ```html
 * 
 * ```
 *
 * ### Styling
 *
 * `` provides the same set of shadow DOM parts and state attributes as ``.
 * See [``](#/elements/vaadin-text-field) for the styling documentation.
 *
 * In addition to `` parts, the following parts are available for theming:
 *
 * Part name         | Description
 * ------------------|-------------------------
 * `increase-button` | Increase ("plus") button
 * `decrease-button` | Decrease ("minus") button
 *
 * Note, the `input-prevented` state attribute is only supported when `allowedCharPattern` is set.
 *
 * See [Styling Components](https://vaadin.com/docs/latest/styling/styling-components) documentation.
 *
 * ### Change events
 *
 * Depending on the nature of the value change that the user attempts to commit e.g. by pressing Enter,
 * the component can fire either a `change` event or an `unparsable-change` event:
 *
 * Value change             | Event
 * :------------------------|:------------------
 * empty => parsable        | change
 * empty => unparsable      | unparsable-change
 * parsable => empty        | change
 * parsable => parsable     | change
 * parsable => unparsable   | change
 * unparsable => empty      | unparsable-change
 * unparsable => parsable   | change
 * unparsable => unparsable | -
 *
 * Note, there is currently no way to detect unparsable => unparsable changes because the browser
 * doesn't provide access to unparsable values of native [type=number] inputs.
 *
 * @fires {Event} input - Fired when the value is changed by the user: on every typing keystroke, and the value is cleared using the clear button.
 * @fires {Event} change - Fired when the user commits a value change.
 * @fires {Event} unparsable-change - Fired when the user commits an unparsable value change and there is no change event.
 * @fires {CustomEvent} invalid-changed - Fired when the `invalid` property changes.
 * @fires {CustomEvent} value-changed - Fired when the `value` property changes.
 * @fires {CustomEvent} validated - Fired whenever the field is validated.
 *
