Clamp node, min-max or range?

I don’t understand the difference beetween min-max and range in the clamp node
https://docs.blender.org/manual/en/latest/render/shader_nodes/converter/clamp.html#id1
Does someone have an explanation ?
Thank you

“Range” will swap Min and Max if needed (i.e. if input connected to Max is actually less than Min).
