BigDecimal初始化小数时，一定要用字符串形式 否则：会出现除法出错 BigDecimal num1 = new BigDecimal(0.1); System.out.println("坑点1：num1="+num1); //坑：num1=0.1000000000000000055511151231257827021181583404541015625 BigDecimal num2 = new BigDecimal(""+0.1);
比较大小compareTo 除法计算设置精确位数和方式，不然除不尽报错 BigDecimal test = new BigDecimal(""+10).divide(new BigDecimal(""+3)); Non-terminating decimal expansion; no exact representable decimal result.
