DoubleFloats.jl -> Double128 | Quad64?

Specific Domains Numerics
6

Well, i really do not get it. I tried :

julia> using Quadmath

julia> using DoubleFloats

julia>  Double128 = DoubleFloats.DoubleFloat{Float128}
DoubleFloat{Float128}

julia> Double128(1)
ERROR: MethodError: no method matching DoubleFloat{Float128}(::Int64)
Closest candidates are:
  DoubleFloat{Float128}(::Real, ::RoundingMode) where T<:AbstractFloat at rounding.jl:200
  DoubleFloat{Float128}(::T) where T<:Number at boot.jl:716
  DoubleFloat{Float128}(::Rational{S}) where {S, T<:AbstractFloat} at rational.jl:113
  ...

I dont get it. typeof(1) == Int64 wich is both smaller than Number and Real :rofl:
