By the way, I was looking for a way to infer a {nonneg R}
from a {i01 R}
.
I can find
[itv of ...]
but not[lb of ...]
, etc.

By the way, I was looking for a way to infer a {nonneg R} from a {i01 R}.
I guess the simplest solution would be to add a Canonical
to be able to write x%:inum%:nng
but the uncomfortable thing is: why would that instance take the lower bound rather than the upper bound? (other than the fact it is probably what one wants most fo the time)
