You can redefine the show method for float. `@which show(stdout, 2/3)` shows you where it is, `@less` prints it. This modification might work:

```julia
julia> function Base.show(io::IO, x::Union{Float64,Float32})
                 Base.Grisu._show(io, round(x, sigdigits=3), Base.Grisu.SHORTEST, 0, get(io, :typeinfo, Any) !== typeof(x), false)
         end

```

(Note, there is a certain danger in redefining Base-methods! But should be ok for `show`)
