I got protein distance data in Julia.  
And it’s like 0.03.9054839648883466.8782495592992210.390223770448832 … etc(millions of data)

 ![image](https://global.discourse-cdn.com/julialang/original/3X/2/6/26fe1c8abf1ce084c5df76490a88a865d29256d0.png)  
And I can’t sort data one by one

It supposed to be 0.0;3.905483964888346;6.87824955929922;10.390223770448832

i can get separated data in julia when i designate specific site

(up in there dm means distance map)

OR if I cannot SPACE data, I want to round data like julia\>round(dm.data; digits=3)

ERROR: MethodError: no method matching round(::Matrix{Float64}; digits=3)  
Closest candidates are:

but this error came out.

Can you help me to do something on this enormous data?

How do you know it is:

```julia
6.87824955929922 ; 10.390223770448832

```

and not:

```julia
6.878249559299221 ; 0.390223770448832

```

Is it by length of decimals? This task feels like it would contain ambiguities like this, especially if very big file.

I also recognize this can be ambiguous, so I got separate data by dm[1,4]=10.390223770448832 …  
but I can’t do it one by one…

Yeah, automating this is important. But how did you manually know which value it was? Are values from a specific range?

It is not clear how you are printing the data, but for the problem with `round` the error indicates that you already have the data in a matrix and so you need to use broadcasting:

```julia
julia> v = [1.023 2.123 3.1]
1×3 Matrix{Float64}:
 1.023 2.123 3.1

julia> round.(v; digits=3)
1×3 Matrix{Float64}:
 1.023 2.123 3.1

```

i.e. using `round.(...)` rather than just `round(...)`
