如何在double变量中划分两个整数？

#include<iostream>
#include <bitset>

int main() {
    int num1 = 10;
    int num2 = 20;

    // 将两个整数转换为二进制字符串
    std::bitset<32> binaryNum1(num1);
    std::bitset<32> binaryNum2(num2);

    // 将两个整数合并为一个double数值
    double mergedNum = (double)((binaryNum1.to_ulong() << 32) | binaryNum2.to_ulong());

    // 输出合并后的double数值
    std::cout << "Merged number: "<< mergedNum<< std::endl;

    // 提取出原始的两个整数
    int extractedNum1 = (int)(mergedNum >> 32);
    int extractedNum2 = (int)(mergedNum & 0xFFFFFFFF);

    // 输出提取出的两个整数
    std::cout << "Extracted numbers: "<< extractedNum1 << ", "<< extractedNum2<< std::endl;

    return 0;
}
