 * A menu item that corresponds to the large number type on the device. These numeric values are generally
 * large enough that they should be stored as big decimals. They have a maximum number of digits and a
 * fixed number of decimal places. They can be positive or negative, although you can prevent negative values
 * by setting negativeAllowed to false.
