Decimal Random Number Generator
Define a minimum, maximum, precision, and count to generate random decimal numbers, along with summary statistics.
How to Use This Calculator
- Enter the minimum and maximum values of the desired range.
- Specify decimal precision (number of digits after the decimal point).
- Choose how many random values to generate.
- Click “Generate” and review the results plus summary statistics.
Formula
Random value = min + (max − min) × U, where U ∼ Uniform(0, 1)
Results truncated/rounded to specified precision
Average and min/max computed from generated sample
Full Description
This random number generator produces decimal samples from a uniform distribution over a specified interval. Flexible precision and count controls make it suitable for simulations, testing, or generating example data.
Frequently Asked Questions
Are values unique?
No. While randomness may yield unique values, duplicates can occur.
Can I export the list?
Copy and paste the results from the output area.
How random is the output?
It relies on JavaScript’s pseudo-random generator, adequate for general simulations but not for cryptographic purposes.
What if I need integers?
Set precision to 0 to obtain integer outputs.
