I am a biologist with no knowledge in programing. I recently started to
write small bits of code to analyze gene co-expression networks. By the
way, congratulations to those who developped Julia and the many available
packages. It's really great and fairly easy to make simple things in a
matter of days with the intuitive Julia syntax.
I am not familar with type management in programing languages but some
behaviors are puzzling for a tenderfoot like myself. Here is a piece of
stupid code just to illustrate my question (I'm using JuliaStudio):
julia> A=[1,2]
2-element Array{Int64,1}:
1
2
julia> typeof([A[1]])
Array{Int64,1}
julia> typeof([A[i] for i=1])
Array{Any,1}
Of course int() is doing the job.
julia> typeof(int([A[i] for i=1]))
Array{Int64,1}
Yet, I find this behavior strange and using int(), float()... makes the code
unnecessarily heavy.
I looked through the posts on julia-users but could not find information about
how to avoid type change during comprehension. Any advice ?
