Re: [julia-users] Re: How to build a range of -Inf to Inf

This is interesting thanks. I didn't realise you could re-assign j inside the index like that. A very neat notational trick. But I agree that looking forward the filter! option is probably best. I'll adjust my code accordingly, many thanks. As an aside, every time I post code to this list I get

Yep. Agreed. Totally redundant :-) Cheers, Colin On 4 June 2016 at 05:11, DNF wrote: > Your in-method is a bit odd: > > Base.in{T}(x::T, r::BasicInterval{T}) = (r.start <= x <= r.stop) ? true : > false > > Why don't you just write > > Base.in{T}(x::T, r::BasicInterval{T}) =

[julia-users] Re: How to build a range of -Inf to Inf

Your in-method is a bit odd: Base.in{T}(x::T, r::BasicInterval{T}) = (r.start <= x <= r.stop) ? true : false Why don't you just write Base.in{T}(x::T, r::BasicInterval{T}) = (r.start <= x <= r.stop) ? The extra stuff is redundant.

[julia-users] Re: How to build a range of -Inf to Inf

Very true. For boring reasons, I actually prefer it that way for my own work (I want errors if the types don't exactly match as it means other parts of my code are doing something unexpected - I like cheap redundant error checks). But I agree that for general use it should work as you suggest.

[julia-users] Re: How to build a range of -Inf to Inf

Looks ok, but I think you could generically have less restricted types in your functions: e.g. 4 in BasicInterval(3.1,4.9) won't work, nor will you be able to construct an interval BasicInterval(3,4.5)

[julia-users] Re: How to build a range of -Inf to Inf

For those interested, I just hacked together the following implementation of what I was after. I've extended in, filter, and replace to the new type: #Type BasicInterval #My own extremely simple interval type that denotes all elements between start and stop immutable BasicInterval{T}
