Beschreibung
When using Complex{Int8} arrays, the functions sum and mean do not make proper type conversion to avoid nasty things :
julia> b = ones(Complex{Int8}, 100000) ;
julia> sum(b)
-96 + 0im
julia> mean(b)
-0.00096 + 0.0im
That seems unconsistent with the behaviour of the same functions on Int8 arrays :
julia> a = ones(Int8, 100000) ;
julia> sum(a)
100000
julia> mean(a)
