If it existed, I would expect to find it as Range#clip or something like 
that. But I don't think it does.

class Range
  def clip(v)
    v < first ? first : v > last ? last : v
  end
end

p (1..10).clip(5)    # 5
p (10..100).clip(5)  # 10 (different to your original post??)
p (1..10).clip(50)   # 10

It wouldn't surprise me if something like this existed in the facets 
library though.

irb(main):001:0> [20,40].min
=> 20
irb(main):002:0> [20,40,30].min
=> 20
irb(main):003:0> [20,40,30].max
=> 40
