This concept has been done many times in the past, under the name "interval arithmetic." Boost has it [1] as does flint [2]

What is really curious is why, after being reinvented so many times, it is not more mainstream. I would love to talk to people who have tried using it in production and then decided it was a bad idea (if they exist).

Interval arithmetic makes good intuitive sense when the endpoints of the intervals can be represented exactly. Figuring out how to do that, however, is not obvious.

Also not all uncertainties are modeled well by uniform distributions over an interval.
