this works in Julia 0.6.2:

```julia
Float32(1.0) |> N0f8
Float32(1.0) |> N0f16

```

this will not work

```julia
Float32(1.0) |> N0f32
Float32(1.0) |> N0f64
Float64(1.0) |> N0f64

```

It looks like when the number of bits is the same or larger, it won’t work.  
error message:

```julia
ArgumentError: FixedPointNumbers.Normed{UInt64,64} is a 64-bit type representing 0 values from 0.0 to 1.0; cannot represent 1.0

```

is this a bug?
