We removed those also because of silence errors. Base.∪
and Base.∩
can be found in generic code for both scalars (not just numbers) and containers, so re-defining it with the interval definition is conflicting.
It is unfortunate how prevalent the union
, intersect
, etc, are in Base.
May I ask why you said that you need it? What is wrong with intersect_interval
and hull
?
from intervalarithmetic.jl.
Hmm I see.
I need them so I can write readable mathematical code :)
from intervalarithmetic.jl.
hehe yes I can sympathise with that :)
In this circonstance, I think the best is to add the following, without importing ∩
and ∪
from Base,
∩(a::BareInterval, b::BareInterval) = intersect_interval(a, b)
∪(a::BareInterval, b::BareInterval) = hull(a, b)
in IntervalConstraintProgramming.jl
Then, you will have your own ∩
and ∪
inside the module, without conflicting with Base.
Of course outside the scope of the module this may still be confusing to have both IntervalConstraintProgramming.:∩
and Base.:∩
.

Huh, interesting idea, thanks!
from intervalarithmetic.jl.
Another possibility is to use \sqcup
and \sqcap
(square versions of the intersection and union symbols), which have no meaning in Julia but are available as symbols that can be defined. Indeed \sqcap
is one of the standard symbols for "interval hull"!
from intervalarithmetic.jl.
Yes we can add symbols to IntervalArithmetic.Symbols
. ⊔
, ⊓
or even ⊍
(\cupdot
), ⩀ (\capdot
).
