자바 큰 수의 사칙연산

*자바 큰 수 사칙연산 (BigInteger)

1. 큰 수의 덧셈 ( add )

import java.util.Scanner;
import java.math.BigInteger;
class Main {
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		
		BigInteger num1 = scanner.nextBigInteger();
		BigInteger num2 = scanner.nextBigInteger();
		scanner.close();
		
		BigInteger temp = num1.add(num2);
		System.out.println(temp);
	}
}

 

2. 큰 수의 뺄셈 ( subtract )

import java.util.Scanner;
import java.math.BigInteger;
class Main {
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		
		BigInteger num1 = scanner.nextBigInteger();
		BigInteger num2 = scanner.nextBigInteger();
		scanner.close();
		
		BigInteger temp = num1.subtract(num2);
		System.out.println(temp);
	}
}

3. 큰 수의 곱셈 ( multiply )

import java.util.Scanner;
import java.math.BigInteger;
class Main {
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		
		BigInteger num1 = scanner.nextBigInteger();
		BigInteger num2 = scanner.nextBigInteger();
		scanner.close();
		
		BigInteger temp = num1.multiply(num2);
		System.out.println(temp);
	}
}

4. 큰 수의 나눗셈 ( divide )

import java.util.Scanner;
import java.math.BigInteger;
class Main {
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		
		BigInteger num1 = scanner.nextBigInteger();
		BigInteger num2 = scanner.nextBigInteger();
		scanner.close();
		
		BigInteger temp = num1.divide(num2);
		System.out.println(temp);
	}
}
