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

public class Main {
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		DecimalFormat df = new DecimalFormat();
		df.applyPattern("0");
		df.setMaximumFractionDigits(8);
		df.setMinimumFractionDigits(8);

		int kaisu = 2;
		long[] num = new long[kaisu];

		for(int i = 0; i < kaisu; i++) {
			num[i] = scan.nextInt();
		}

		long d = num[0] / num[1];
		long r = num[0] % num[1];
		double nf = num[0] / (double)num[1];
		Double objf = new Double(nf);
		String f = df.format(objf);
		System.out.println(d + " " + r + " " + f);
