A Random Number adds a simple random number generator to WordPress. Add the “A Random Number” block in the block editor, or put the [arandomnumber] shortcode in any post, page or widget, and it prints a new random number every time the page loads. Use it as many times as you like on the same page.

Features

Gutenberg block with minimum, maximum and thousands-separator settings and a live preview
Random number generator shortcode for posts, pages and text widgets
Custom range with the min and max attributes (default 1 to 100)
Negative numbers and large ranges are supported
Thousands separators on by default, switch them off with comma=no
Insert button in the classic editor (visual and text mode)
No settings page and no database tables to manage

How to use

In the block editor click the add-block button, search for “A Random Number” and set the range in the block sidebar.

Or add the shortcode wherever you want the number to appear. The default range is 1 to 100.

[arandomnumber]

Pick your own range with min and max:

[arandomnumber min=1 max=10000]

This prints a number between 1 and 10,000, for example 8,014.

[arandomnumber min=-500 max=-1]

This prints a number between -500 and -1, for example -232.

[arandomnumber min=50000000 max=60000000]

This prints a number between 50,000,000 and 60,000,000, for example 56,449,060.

To print the number without thousands separators use comma=no:

[arandomnumber min=100000 max=999999 comma=no]

This prints something like 456245.
