Java 中的 BigInteger 上的数学运算

让我们使用 Java 中的内置方法对 BigInteger 执行以下运算。

Addition: add() method
Subtraction: subtract() method
Multiplication: multiply() method
Division: divide() method

让我们创建三个 BigInteger 对象。

BigInteger one = new BigInteger("98765432123456789");
BigInteger two = new BigInteger("94353687526754387");
BigInteger three = new BigInteger("96489687526737667");

对它们应用数学运算。

one = one.add(two);
System.out.println("Addition Operation = " + one);
one = one.multiply(two);
System.out.println("Multiplication Operation = " + one);

以下是一个示例 −

import java.math.BigInteger;
public class Main {
   public static void main(String[] args) {
      BigInteger one = new BigInteger("98765432123456789");
      BigInteger two = new BigInteger("94353687526754387");
      BigInteger three = new BigInteger("96489687526737667");
      one = one.add(two);
      System.out.println("Addition Operation = " + one);
      one = one.multiply(two);
      System.out.println("Multiplication Operation = " + one);
      two = three.subtract(two);
      System.out.println("Subtract Operation = " + two);
      two = three.divide(two);
      System.out.println("Division Operation = " + two);
   }
}

输出

Addition Operation = 193119119650211176
Multiplication Operation = 18221501070917918273532554434429112
Subtract Operation = 2135999999983280
Division Operation = 45
