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

```
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:

```
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

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

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

```
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
```
