Random Integer Generator

This form allows you to generate random integers. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.

Part 1: The Integers

Generate random integers (maximum 10,000).

Each integer should have a value between and (both inclusive; limits ±1,000,000,000).

Format in column(s).

Part 2: Choose Numeral System

How should the integers be displayed?
Hexadecimal (base 16)
Decimal (base 10)
Octal (base 8)
Binary (base 2)

Part 3: Choose Output Format

How do you want the integers to be shown?
On a nicely formatted web page (type text/html)
As a bare-bones text document (type text/plain)

Part 4: Choose Randomization

Do you want a new randomization or one that was prepared earlier? [explain this]
Generate your own personal randomization right now
Use pregenerated randomization from
Use pregenerated randomization based on persistent identifier (max 64 alphanumeric characters)

Part 5: Go!

Be patient! It may take a little while to generate your numbers...

Note: The numbers generated with this form will be picked independently of each other (like rolls of a die) and may therefore contain duplicates. There is also the Sequence Generator, which generates randomized sequences (like raffle tickets drawn from a hat) and where each number can only occur once.
