The shortcode [arandomnumber] can be added to any post, page, or widget as many times as needed to display a random number. The number has a default range of 1 – 100, but can be changed using the min and max attributes, like so:
[arandomnumber min=1 max=10000]: This will output a random number between 1 and 10,000. (Like this: 8,014) 
[arandomnumber min=-500 max=-1]: This will output a random number between -500 and -1. (Like this: -232) 
[arandomnumber min=50000000 max=60000000]: This will output a random number between 50,000,000 and 60,000,000. (Like this: 56,449,060)
etc.
If you wish to disable commas, use the comma=no attribute, like so: [arandomnumber min=100000 max=999999 comma=no]. This will output a random number within the range without the commas, like this: 456245.
