java - 数学难度

Question

当我输入 1000 投资金额 4.25 月利率和 1 年，为什么我得到的结果是 4.384414858452464E11 而不是预期的 1043.34？

import java.util.Scanner;

public class FinancialApplicationFutureInvestment_13 {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.println("Enter investment amount: ");
        int investmentAmount = input.nextInt();
        System.out.println("Enter monthly interest rate: ");
        double monthlyInterestRate = input.nextDouble();
        System.out.println("Enter number of years");
        int numOfYears = input.nextInt();

        double futureInvestmentValue = investmentAmount *
            (Math.pow(1 + monthlyInterestRate, numOfYears * 12));
        System.out.println("Accumulated value is: " + futureInvestmentValue);

        double test = Math.pow(1 + monthlyInterestRate, numOfYears * 12);
        System.out.println(test);
    }
}
