BigDecimal进行比较

 public int compareTo(BigDecimal val) {        // Quick path for equal scale and non-inflated case.        if (scale == val.scale) {            long xs = intCompact;            long ys = val.intCompact;            if (xs != INFLATED && ys != INFLATED)                return xs != ys ? ((xs > ys) ? 1 : -1) : 0;        }        int xsign = this.signum();        int ysign = val.signum();        if (xsign != ysign)            return (xsign > ysign) ? 1 : -1;        if (xsign == 0)            return 0;        int cmp = compareMagnitude(val);        return (xsign > 0) ? cmp : -cmp;    }

eg:

a.comparedTo (b)

  如果a大于b返回1;

 如果a小于b返回-1;

如果a等于b返回0;
