 * Convert RMB from lowercase to uppercase

 * @param bool $is_round Whether to decimal Rounding
 * @param bool $is_extra_zero Whether to end the integer part with 0 and add 0 to the decimal number, such as 1960.30,
 * Some systems require the output of "One thousand nine hundred six hundred yuan zero three cents", in fact" "One thousand, nine hundred, ten yuan and three cents" is also correct
