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 Ruby (judge verdict: Wrong Answer)

require 'bigdecimal'
a, b = gets.chomp.split(' ').map(&:to_i)
d = a / b
r = a % b
f = BigDecimal(a.to_s) / 2
printf("%d %d %.5f\n", d, r, f)
