Can I generate multiple random numbers at once?

Yes! Set the count parameter to generate up to 1000 random numbers in a single click. Perfect for bulk data generation.

How do I generate unique random numbers?

Enable the 'Unique' option to ensure no duplicate numbers are generated. Great for lottery-style draws, raffle tickets, and creating random samples.

Can I get decimal numbers?

Set the precision parameter to control decimal places. Precision=1 gives tenths (1.5), precision=2 gives hundredths (1.25), etc.

What does the step parameter do?

Step controls the increment between possible values. Step=1 gives integers (1,2,3), step=0.5 gives halves (1.0,1.5,2.0), step=10 gives multiples of 10.

Can I sort the generated numbers?

Yes! Choose ascending (lowest to highest), descending (highest to lowest), or leave unsorted for completely random order.

What's the maximum count I can generate?

You can generate up to 1000 numbers at once. For unique generation, the count cannot exceed your range size.

Is this suitable for scientific sampling?

Yes! Our CSPRNG provides cryptographically secure randomness suitable for statistical sampling, research, and scientific applications.
