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'

def itp1_4a()
  num=STDIN.gets.chomp.split(/ /)
  print "#{num[0].to_i/num[1].to_i} #{num[0].to_i%num[1].to_i} "
  print "#{(BigDecimal(num[0])/BigDecimal(num[1])).to_f}\n"
end

itp1_4a()
