使用BigDecimal转换较长小数时候出现科学计数法的问题

1     public static String divToString(double v1, double v2, int scale){
2         if (scale < 0) {
3             throw new IllegalArgumentException(
4                     "The scale must be a positive integer or zero");
5         }
6         BigDecimal b1 = new BigDecimal(Double.toString(v1));
7         BigDecimal b2 = new BigDecimal(Double.toString(v2));
8         return  b1.divide(b2, scale, BigDecimal.ROUND_HALF_UP).toString();
9     }

只要将BigDecimal 对象toString()就好。
