Java 代码实现浮点数向上取整

import java.util.Scanner;

public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); double f = scanner.nextDouble(); int result; if (f >= 0) { result = (int) Math.ceil(f); } else { result = (int) Math.floor(f); } System.out.println(result); } }
