input_description: Input is given from Standard Input in the following format:
  
      
      
      A B
attempt: A, B = map(float, input().split())
  A = int(round(A))
  B_0 = B // 1
  B_1 = B % 1
  ans_0 = round(A * B_0)
  ans_1 = A * round(B_1 * 100) // 100
  print(int(round(ans_0 + ans_1)))
  
problem_description: Statement
  
  Compute A \times B, truncate its fractional part, and print the result as an
  integer.
