JAVA大数运算

java大数是个好东西,用起来方便,代码短.

代码如下:

import java.util.*;
import java.math.*;
public class Main {
    public static void main(String args[]) {
        Scanner cin = new Scanner(System.in);
        BigInteger a , b;
        while(cin.hasNext()) {
            a = cin.nextBigInteger();
            b = cin.nextBigInteger();

            System.out.println(a.add(b));    //加法

            System.out.println(a.subtract(b));    //减法

            System.out.println(a.multiply(b));    //乘法

            System.out.println(a.divide(b));    //除法

            System.out.println(a.remainder(b));    //取模

            System.out.println(a.abs());    //绝对值

            System.out.println(a.pow(10));    //x次幂

            int bit = 16;
            System.out.println(a.toString(bit));    //转化为bit进制
        }
    }
}
