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: Wrong Answer)

import java.util.*;
import java.math.BigDecimal;
public class Main{
public static void main(String[] args){
	Scanner sc = new Scanner(System.in);
	int a = sc.nextInt();
	int b = sc.nextInt();
	int d = a / b;
	int r = a % b;
	float a_f = (float)a;
	float b_f = (float)b;
	float f =  a_f / b_f ;
			int x = a / b;
		float r_f = (float)r ;
		float y = r_f / b_f;
		
			float z = x + y;
		BigDecimal bd = new BigDecimal(z);
		if (y ==0.5){System.out.println(d + " " + r + " " + x + ".5");}
		else{
		BigDecimal bd3 = bd.setScale(6, BigDecimal.ROUND_DOWN);
			System.out.println(d + " " + r + " " + bd3);}
		
	}
