     * 人民币数值转中文大写
     * @author SunsCheung
     * @time 2015.11.11
     * @param string $number 数值 默认为0
     * @param string $int_unit 币种单位，默认"元"，有的需求可能为"圆"
     * @param bool $is_round 是否对小数进行四舍五入
     * @param bool $is_extra_zero 是否对整数部分以0结尾，小数存在的数字附加0,比如1960.30，
     *             有的系统要求输出"壹仟玖佰陆拾元零叁角"，实际上"壹仟玖佰陆拾元叁角"也是对的
     * @param bool $dec_to_int 是否对让小数部分进位到个位，如果进位，个位加1，小数为0，
     * @return string
