/**
* __PrimeFaces InputNumber Widget__
*
* InputNumber formats input fields with numeric strings. It supports currency symbols, minimum and maximum value,
* negative numbers, and a lot of round methods.
*
* @typedef {import("autonumeric").Options} PrimeFaces.widget.InputNumber.AutoNumericOptions Alias for the AutoNumeric
* options, required for technical reasons.
*
* @prop {import("autonumeric")} autonumeric The current AutoNumeric instance.
* @prop {boolean} disabled Whether this widget is currently disabled, i.e. whether the user can enter a number.
* @prop {JQuery} hiddenInput The DOM element for the hidden input field with the current value of this widget.
* @prop {JQuery} input The DOM element for the visible input field with autoNumeric.
* @prop {undefined} plugOptArray Always `undefined`.
* @prop {string} valueToRender The initial, numerical value that is displayed, such as `0.0` or `5.3`.
*
* @interface {PrimeFaces.widget.InputNumberCfg} cfg The configuration for the {@link InputNumber| InputNumber widget}.
* You can access this configuration via {@link PrimeFaces.widget.BaseWidget.cfg|BaseWidget.cfg}. Please note that this
* configuration is usually meant to be read-only and should not be modified.
* @extends {PrimeFaces.widget.BaseWidgetCfg} cfg
* @extends {PrimeFaces.widget.InputNumber.AutoNumericOptions} cfg
*
* @prop {boolean} cfg.disabled Whether this widget is initially disabled.
* @prop {undefined} cfg.pluginOptions Always undefined.
* @prop {string} cfg.valueToRender The initial, numerical value that is displayed, such as `0.0` or `5.3`.
