Here, my point is the word "Abstract"

They are the same. The vector is just a type alias for the array of size 1.
Personally I like vector because to me it is clearer to read.

Is `function sum{T<:FloatingPoint}(x::AbstractArray{T,1}) ` or
`function sum{T<:FloatingPoint}(x::AbstractVector{T}) ` better?

Thank's a lot, that is cool.

I would simply go with:
function mysum{T<:FloatingPoint}(x::Vector{T}) sum(x) end
Re: [julia-users] Re: How to define an array of floating point numbers?
Hi,
I think this does what you want:
function sum{T<:FloatingPoint}(x::Array{T,1})
println("hi")
end
Cheers,
Rene

[julia-users] Re: How to define an array of floating point numbers?
Ok, the following works for 0.3 and 0.4:
FloatArray = Union(Array{Float32, 1}, Array{Float64, 1})
Is this the best way to define an array of floating point numbers?

Ok, the following definition works on Julia 0.4, but not with 0.3:
FloatArray = Union{Array{Float32, 1}, Array{Float64, 1}}
function sum(x::FloatArray).
Any idea?
