大数运算法则

public static void main(String[] args) {?

??????? BigInteger aa =new BigInteger("100");

??????? BigInteger bb= new BigInteger("25");?

??????? BigInteger sub=aa.subtract(bb);//大整数的减

??????? BigInteger add=aa.add(bb);//大整数的加?

??????? BigInteger mul=aa.multiply(bb);//大整数的乘

??????? BigInteger div=aa.divide(bb);//大整数的除?

??????? System.out.println(sub.toString());? ??????? System.out.println(add.toString()); ??????? System.out.println(mul.toString()); ??????? System.out.println(div.toString()); }
