Have you tried str() should convert strings or floats.

Weirdly this isnt required for println as it auto converts.

what are you trying to achieve your code already displays the values in the array.

![image](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/e/e6872c52aeed3d335dc616655133ed3bb14b1aaa.png)

`if(i*44<width)text(x[i],i*44,55);`

this will limit the displayed number to only those that fit in the window, note the array values are still being iterated though.

Your iterating through a double array so you need the length of the internal array.

The code however is assuming that all internal arrays are the same size, else use `x[i].length`

Using @paulgoux suggestion for using String, I wonder if this too is of use to your question. Then you don’t need to use the array and for loop…  
🤔

//////////////////////////////////////////////

```auto
void setup () { 
  size (800, 800);

void draw () { 

  fill(0);

  String strg1 = "50, 61, 83, 69, 71, 50, 29, 31, 17, 39, 50, 61, 83, 69, 71, 50, 29, 31, 17, 39, 50, 61, 83, 69, 71, 50, 29, 31, 17, 39, 50, 61, 83, 69, 71, 50, 29, 31, 17, 39"; // I did not include all of your numbers, this is just a text to see if solves the question

  textSize(20);
  text(strg1, 20, 40, 750, 750);
