While Min[Interval[...]] and Max[Interval[...]] work both fine. The new function MinMax[Interval[...]] does not work.
I was wondering why not? Is it simply forgotten? Or is there another design-decision behind this choice?
Thanks for forwarding! I guess they kinda forgot it…It is quite easily overlooked as in the help of Min the Min[Interval[]] is not discussed, only a small semi-hidden note in the Interval help.
