= Julia Arrays =

Julia supports '''single-''' and '''multi-dimensional arrays'''.

<<TableOfContents>>

== Declaration ==

{{{
julia> [1,2,3]
3-element Vector{Int64}:
 1
 2
 3
}}}

Arrays take the common type of all their elements. If the elements are not of the same type but have a common [[Julia/DataTypes#Promotion|promotion type]], the elements are recast.

{{{
julia> [1, 2.3, 4//5]
3-element Vector{Float64}:
 1.0
 2.3
 0.8
}}}

Elements can also be explicitly recast at declaration of an array.

{{{
julia> Float32[1, 2.3, 4//5]
3-element Vector{Float32}:
 1.0
 2.3
 0.8
}}}
