get(callback = null) {
        return this.getNumericString(callback);
    }
Alias of the `getNumericString()` function.
Developers should use one of the more explicit function names to get what they want :
- a numeric string : `getNumericString()`
- a formatted string : `getFormatted()`
- a number : `getNumber()`, or
- a localized numeric string : `getLocalized()`

@usage anElement.get();

@param {function|null} callback If a callback is passed, then the result is passed to it as its first argument, and the AutoNumeric object has its second

@deprecated
@returns {string|null}
