const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void async function () {
    // Write your code here
  while(line = await readline()) {
        // 读取输入并转换为数字
        let num = parseFloat(line);
        
        // 使用Math.round进行四舍五入
        let rounded = Math.round(num);
        
        // 输出结果
        console.log(rounded);
    }
}()
