From Rosetta Code

Ulam spiral (for primes)

The task requirement for the Rosetta Code task   Ulam spiral (for primes)   was to choose a grid size that would fill up your terminal screen.

Could you increase the last   (Lau)   output to at least,   for instance,   to maybe fill up at least a screen size of 80×80, or even bigger?

I realize that there are other computer programming language entries that didn't comply with a full-screen version,   and I hesitate of causing a ruckus with a whole bunch of users,   but I thought I would prompt you   (off-task, so to speak)   and see if I could persuade you a bit to enlarge your Ulam spiral ASCII plot.


Thanks.       -- Gerard Schildberger (talk) 22:14, 6 July 2020 (UTC)

Template:Reply toTemplate:Ping Happy to oblige. Many tasks seemingly attempt to minimize the output section (to barely a "proof-of-concept" exhibit) and having glanced at the other submissions I just sort of assumed that was the case here too, but it looks much better with larger output. :) --Davbol (talk) 14:27, 7 July 2020 (UTC)
Thanks for your time and understanding.     -- Gerard Schildberger (talk) 14:32, 7 July 2020 (UTC)


a method of displaying a largish plot to have a smaller display

There is a method to display large plots and have a smaller display. Instead of:

This will allow you to use a bigger plot with the same footprint as your original (at 100%).


You can use   50%,   for the font-size,   but then the normal display of the text:

n = 66.0

will be reduced as well,   and almost unreadable.     -- Gerard Schildberger (talk) 14:57, 7 July 2020 (UTC)

Thanks. I had just recently learned that "trick" (used it on Sierpinski pentagon). I could go nuts and do a 1000x1000 spiral shown at 10% -- it works fine at that scale, but would likely frustrate visitors with the >2M increase in page size if embedded in the wiki!
