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.*;

public class Main {
	public static void main(String args[]) {
		Scanner scan = new Scanner(System.in);
		int a, b;
		a = scan.nextInt();
		b = scan.nextInt();

		// ???????°???°?????°??¨?????\???????????¨???
		double d;
		d = 0.0;

		// a??b ?????´??°???????¨????
		System.out.print(Integer.toString(a / b) + " ");
		// a??b????????? ?????´??°???????¨????
		System.out.print(Integer.toString(a % b) + " ");
		// a??b??????????°???°?????°???????¨????
		// a????????????.0???????????????
		d = Double.parseDouble(Integer.toString(a) + ".0");

		BigDecimal x = new BigDecimal(d / b);

		System.out.print(x.setScale(5, BigDecimal.ROUND_HALF_UP));
