About this tool

Made for the task at hand.

Pick random values for sampling, testing, and simulations without Math.random modulo bias. Define inclusive integer bounds or generate decimal values with six digits after the decimal point.

How to use

  1. Enter the minimum and maximum separated by a comma or space.
  2. Choose integers or decimals and set the quantity.
  3. Generate the values and copy the complete list.

Common questions
Are both integer bounds included?

Yes. Integer generation includes both the minimum and maximum, and rejection sampling keeps every value in the range equally likely.

Is this suitable for scientific simulations?

It uses a cryptographic random source, but scientific work may require a specified algorithm, seed, and reproducible distribution that this simple tool does not provide.
