示例1: toNumber

* Returns a locale formatted number depending on the given options.
* The seperation and fraction sign is used from the set locale.
* ##0.# -> 12345.12345 -> 12345.12345
* ##0.00 -> 12345.12345 -> 12345.12
* ##,##0.00 -> 12345.12345 -> 12,345.12
*
* @param string $input Localized number string
* @param array $options Options: number_format, locale, precision. See {@link setOptions()} for details.
* @throws \Zend\Locale\Exception\InvalidArgumentException
