Why does the following prints 4.0 but prints 60.0 when the statement
in durationInMinutes s changed to

@duration  value*60).to_i
or
self.duration  value*60).to_i?

I thought it should print 60.0 in all three cases.



----------------------------------

class Song
  attr_reader :name, :artist, :duration
  attr_writer :duration, :artist

  def initialize(name1, artist1, duration1)
    @name    ame1
    @artist  rtist1
    @duration  uration1
  end

  def to_s
    "Song: #{@name}--#{@artist} (#{@duration})"
  end

  def durationInMinutes
    duration/60.0
  end

  def durationInMinutesalue)
    duration  value*60).to_i
  end

end

aSong  ong.new("New Song", "New ArtistShadows", 240)
aSong.durationInMinutes  0.0
print aSong.durationInMinutes.to_s
