102260: [AtCoder]ABC226 A - Round decimals

Problem Statement

You are given a real number $X$, which is representable using at most three decimal digits, with three decimal digits.
Round $X$ to the nearest integer and print the result.

Constraints

• $0 \leq X < 100$
• $X$ is representable using at most three decimal digits.
• $X$ has three decimal digits in input.

Input

Input is given from Standard Input in the following format:

$X$

Output

Print the integer resulting from rounding $X$ to the nearest integer.

Sample Input 1

3.456

Sample Output 1

3

The digit in the first decimal place of $3.456$ is $4$, so we should round it down to $3$.

Sample Input 2

99.500

Sample Output 2

100

Sample Input 3

0.000

Sample Output 3

0

问题描述

给你一个实数$X$，可以用最多三个小数位数表示，最多有三个小数位数。
将$X$四舍五入到最接近的整数并打印结果。

约束条件

• $0 \leq X < 100$
• $X$可以用最多三个小数位数表示。
• 输入中$X$有三个小数位数。

输入

输入从标准输入以以下格式给出：

$X$

输出

打印将$X$四舍五入到最接近的整数的结果。

样例输入1

3.456

样例输出1

3

$3.456$的第一个小数位数是$4$，所以我们应该向下取整到$3$。

样例输入2

99.500

样例输出2

100

样例输入3

0.000

样例输出3

0
