Description
rand throws an InexactError when called on multi-dimensional DomainSets of Ints
Examlple
rand(1..10) returns a Float64 between 1 and 10
rand((1..10) × (1..10)) throws InexactError: Int64(random float)
If 1..10 is supposed to be continuous, I guess (1..10) × (1..10) should too.
Note that
typeof(1..10) is IntervalSets.ClosedInterval{Int64}
and typeof((1..10) × (1..10)) is DomainSets.Rectangle{SVector{2, Int64}}
suggesting that these are intervals of integers, so rand would maybe give an integer ? Or else, 1..10 should automatically convert it's type to float ?

Research direction
Start by reproducing the reported rand(1..10) and rand((1..10) × (1..10)) cases, then trace the rand entry point for DomainSets.Rectangle. Done means the multidimensional case has defined behavior for integer intervals and no longer raises the reported InexactError.
