java.lang.ArithmeticException: / by zero at java.math.BigDecimal.divideAndRound

BigDecimal 除某个数等于零然后就报错了那么问题来了有零这种情况怎么办呢

 BigDecimal num = BigDecimal.valueOf(Double.valueOf(m.get("num").toString()));
            double completedDouble = Double.valueOf(m.get("completed").toString());
            BigDecimal completed =  num.divide(BigDecimal.valueOf(completedDouble),2, RoundingMode.CEILING);

ERROR c.i.e.handler.GlobalExceptionHandler - java.lang.ArithmeticException: / by zero

酱紫判断可以解决

 if(BigDecimal.ZERO.compareTo(completed) == 0){
                completed = BigDecimal.ZERO;
            }
