Random Decimal Fraction Generator

This form allows you to generate random decimal fractions in the [0,1] interval. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.

Step 1: The Fractions

Generate random decimal fractions (maximum 10,000) from a uniform distribution across the [0,1] interval.

Use decimal places (maximum 20).

Format in column(s).

Step 2: Choose Output Format

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

Step 3: 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)

Step 4: Go!

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

Note: The numbers generated with this form will be picked independently of each other (like rolls of a die) and may therefore contain duplicates.
