Can I generate decimal fractions outside the 0 to 1 range?

No, the tool is designed specifically to produce values within the [0,1] interval. For other ranges, you would need to apply a scaling formula to the generated numbers.

How is the randomness different from a standard computer random function?

RANDOM.ORG uses atmospheric noise as its source of randomness, which is considered true randomness, whereas most computer programs rely on mathematical algorithms that produce pseudo-random sequences.

Is there a limit to how many decimal fractions I can generate at once?

The tool operates within the limits of your RANDOM.ORG quota. Users should check their account status for current generation limits.

Can I use these generated numbers for scientific publications?

Yes, because the numbers are derived from a verified physical source of randomness, they can be cited as true random data in research contexts, provided you reference RANDOM.ORG as the source.
