ceil()
函数是 C++ 标准库 <cmath>
中的一个函数,用于计算大于或等于给定浮点数的最小整数
#include<iostream>
#include <cmath>
int main() {
double num = 5.6;
int upper_bound = std::ceil(num);
std::cout << "Upper bound of "<< num << " is: "<< upper_bound<< std::endl;
return 0;
}
#include<iostream>
#include <cmath>
int main() {
double num1 = 7.3;
double num2 = 2.8;
double difference = num1 - num2;
int upper_bound = std::ceil(difference);
std::cout << "Upper bound of the difference between "<< num1 << " and "<< num2 << " is: "<< upper_bound<< std::endl;
return 0;
}
#include<iostream>
#include <cmath>
int main() {
int total_items = 45;
int items_per_page = 10;
int total_pages = std::ceil(static_cast<double>(total_items) / items_per_page);
std::cout << "Total pages: "<< total_pages<< std::endl;
return 0;
}
这些示例展示了如何使用 ceil()
函数解决实际编程问题。请注意,在使用 ceil()
函数时,确保包含 <cmath>
头文件。
