I’m new to Julia, and was trying to find a way to define a half-open interval like (-Inf, 5.0], then test if a floating point number is contained therein. In Swift I could do let leftOpenInterval = ...5.0 print(leftOpenInterval.contains(-Double.infinity)) // true print(leftOpenInterval.contains(3…

Is Interval{Float64,Closed,Closed}(-Inf, 5.) what you want? (-Inf..5.0 for short)

Thank you for the link. However, I can’t seem to find an example of how to define the kind of unbounded interval in my OP. If I try to mirror the example Interval{Closed,Closed}(1, 10) and try out Interval{Float64, Unbounded, Closed}(1, 5.0) or Interval{Float64, Unbounded, Closed}(5.0) (or any vari…

Indeed it is. Thank you very much! :slight_smile:

IntervalSets.jl also works: julia> using IntervalSets julia> 5.0..Inf 5.0..Inf julia> 6.0 ∈ 5.0..Inf true

What’s the difference? When should you use one vs the other?

How can I define a half-open interval in Julia, and test for containment?

Not, sure but some discussion and links here: Intervals.jl vs IntervalSets.jl?
