Type a minimum and a maximum, and this random number generator fills a list with numbers from that range. Both ends are included, negative numbers work, and you can draw up to 100 at a time. Out of the box you get 12 whole numbers between 1 and 1,000, with no repeats.
The numbers are made on your device using the browser's crypto.getRandomValues, the same source Randomly's password generator uses. Your settings are remembered in this browser, and a link such as ?min=1&max=6&count=1 opens the tool already set up.
What a random number generator does
It picks numbers so that, in whole-number mode, every value in your range has the same chance. That matters whenever choosing by hand would let habits creep in, because people picking numbers in their head tend to favor some without noticing.
How to use the random number generator
- Enter a minimum and a maximum. Both are included.
- Set the Count slider from 1 to 100.
- Open Advanced to switch to decimals, sort the results or allow duplicates.
- The list redraws whenever you change a setting. Click Regenerate for a fresh draw.
- Tap a number to copy it, or use Copy CSV or Copy as list.
Integer or decimal, sorted or not
Advanced has three settings. Type switches between Integer and Decimal, and in Decimal mode a Precision slider sets 1 to 8 decimal places. Sort puts the list in ascending or descending order. Allow duplicates is off by default, so each whole number appears once, until you ask for more numbers than the range holds. Then repeats come back on automatically, since there's no other way to fill the list. Decimal draws aren't checked for repeats.
Open Show stats under the results for the sum, mean, lowest and highest value, and how many are unique.
