Hi, I would like to align the column (v), how do I do it?

```julia
vect_mov = reshape(a,3,nno)' # matrix 3x4

for i = 1:nno
   
   u = (round(1000*vect_mov[i,1], digits = 3))
   v = (round(1000*vect_mov[i,2], digits = 3))
   
   println("Node $i: u = $u v = $v ")
            
end

```

One way is to use `@printf` the good old C style method:

```julia
using Printf

vect_mov = rand(3,4);
for i = 1:3
    @printf("Node %d: u = %7.3f v = %7.3f\n", i, round(1000*vect_mov[i,1], digits = 3), 1000*vect_mov[i,2]) 
end

```

which gives

```julia
Node 1: u = 860.360 v = 182.717
Node 2: u = 301.294 v = 138.291
Node 3: u = 178.381 v = 210.087

```

It’s wonderful, thanks

Fyi, an alternative **without** Printf, just for fun:

```julia
vect_mov = rand((0.0,2.097, 7.09, 13.1291, -10.161), 3, 4)
for i = 1:3
   u, v = round.((vect_mov[i,1],vect_mov[i,2]), digits=3)
   is = rpad.(string.(i), 2)
   us, vs = rpad.(string.((u,v)),8)
   println("Node $is: u = $us, v = $vs")
end

Node 1 : u = 13.129 , v = 2.097   
Node 2 : u = 0.0 , v = 0.0
Node 3 : u = -10.161 , v = -10.161

```
