Dear all, I am just starting to use Julia and I run into the following issue [Julia Version 1.4.1 (2020-04-14)]:
```julia
julia> arr = [-498796.2749933266 408222.59838380764 -583210.404155956 266966.3188608052];
julia> arr
1×4 Array{Float64,2}:
-498796.0 408223.0 -583210.0 266966.0
julia> print(arr)
[-498796.2749933266 408222.59838380764 -583210.404155956 266966.3188608052]
```
Notice that in the second output, all numbers are incorrectly rounded to “.0”.
But with 1D array this works as expected:
```julia
julia> arr = [-498796.2749933266; 408222.59838380764; -583210.404155956; 266966.3188608052];
julia> arr
4-element Array{Float64,1}:
-498796.2749933266
408222.59838380764
-583210.404155956
266966.3188608052
```
Am I doing something wrong, or should I report a bug?

It’s just printing them in a compact form, so that more columns can fit into the screen. (For example `rand(9,9)` fits into a window 100 characters wide.) As you’ve noticed, it doesn’t do this for vectors, since there is nothing to be gained.

That’s true, but the `.0` is just wrong. Displaying `-498796` would be correct (rounding to the nearest integer), but displaying `-498796.0` is wrong–it should be `-498796.3`.
I’ve verified that this exists in Julia 1.4.2 and in the 1.5 beta.

I’ve opened an issue: [Floats print with incorrect rounding in compact context · Issue #36234 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/36234)

Oh I see, sorry, the complaint is that it’s rounding to 0 digits when there is space for 1:
```julia
julia> round(arr[2], digits=0)
408223.0
julia> round(arr[2], digits=1)
408222.6
```

Yeah, exactly. It’s that when we round to 0 digits, we still have a `Float64`, and an integral `Float64` is always printed with `.0`. That implies (to my human brain) that `.0` is a significant digit of the value, but that’s not the case.
The solution might be to never round to exactly 0 digits when printing in compact mode.
