Round a ruby float up or down to the nearest 0.05

Question

I'm getting numbers like

2.36363636363636
4.567563
1.234566465448465
10.5857447736

How would I get Ruby to round these numbers up (or down) to the nearest 0.05?

Check this link out, I think it's what you need. Ruby rounding

class Float
  def round_to(x)
    (self * 10**x).round.to_f / 10**x
  end

  def ceil_to(x)
    (self * 10**x).ceil.to_f / 10**x
  end

  def floor_to(x)
    (self * 10**x).floor.to_f / 10**x
  end
end
