Hj7 take approximate value

describe

Write a program , Accept a positive floating point number , Output the approximate integer value of this value . If the value after the decimal point is greater than or equal to 0.5 , Rounding up ; Less than 0.5 , Then round down .

Data range ： Make sure that the number entered is in 32 Bit floating point number range

Input description ：

Enter a positive floating point number

Output description ：

Output the approximate integer value of this value

Example 1

Input ：5.5

Output ：6

explain ：0.5>=0.5, therefore 5.5 Need to round up to 6

Example 2

Input ：2.499

Output ：2

explain ：0.499<0.5,2.499 Round down to 2

Algorithm implementation

/**
 Ideas ：
1. establish Scanner Class to receive input statements , Enter positive floating point type , And output the corresponding results ;
2. Can force conversion int type 
3. You can take the rest 
4. Can function ：
*/
import java.util.Scanner;
