Problem:
A/B Problem

Write a program which reads two integers a and b, and calculates the following values:

a ÷ b: d (in integer)

remainder of a ÷ b: r (in integer)

a ÷ b: f (in real number)

Input

Two integers a and b are given in a line.

Output

Print d, r and f separated by a space in a line. For f, the output should not contain an absolute error greater than 10-5.

Constraints

1 ≤ a, b ≤ 109

Sample Input 1

3 2

Sample Output 1

1 1 1.50000

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
import java.math.BigDecimal;

public class Main {

	public static void main(String[] args) {
		// TODO ?????????????????????????????????????????????
		
		Scanner scan = new Scanner(System.in);
        int a = scan.nextInt();
        int b = scan.nextInt();
		int d = a/b;
		int r = a%b;
		double x = a;
		double y = b;
		double f = x/y;
		
		BigDecimal z = new BigDecimal(f);
		BigDecimal z1 = z.setScale(5, BigDecimal.ROUND_HALF_UP);

		System.out.print(d + " " + r + " ");
		System.out.printf("%.5f",z1);
	}
