* 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
