BigDecimaldivide除法除不尽报错的问题及解决

BigDecimal a = new BigDecimal(10);
BigDecimal re = a.divide(new BigDecimal(3));
System.out.println(re);

BigDecimal a = new BigDecimal(10);
BigDecimal re = a.divide(new BigDecimal(3)).setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println(re);

BigDecimal a = new BigDecimal(10);
BigDecimal re = a.divide(new BigDecimal(3),2,BigDecimal.ROUND_HALF_UP);
System.out.println(re);

try {
