法律研究Java 中的 BigInteger 上的數學運算
讓我們使用 Java 中的內建方法對 BigInteger 執行以下運算。
Addition: add() method Subtraction: subtract() method Multiplication: multiply() method Division: divide() method
讓我們建立三個 BigInteger 物件。
BigInteger one = new BigInteger("98765432123456789");
BigInteger two = new BigInteger("94353687526754387");
BigInteger three = new BigInteger("96489687526737667");對它們應用數學運算。
one = one.add(two);
System.out.println("Addition Operation = " + one);
one = one.multiply(two);
System.out.println("Multiplication Operation = " + one);以下是一個示例 −
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);
}
}輸出
Addition Operation = 193119119650211176 Multiplication Operation = 18221501070917918273532554434429112 Subtract Operation = 2135999999983280 Division Operation = 45
