How to use Random Number Generator
- Enter a minimum and maximum, then choose whole numbers or decimal numbers.
- Choose the quantity and whether repeated values are allowed. Set decimal places if needed.
- Generate the list, optionally sorted, then copy or download it.
A closer look
Whole-number mode samples the integers inside your inclusive bounds. Decimal mode samples evenly spaced values at your selected precision: two decimal places uses steps of 0.01. For example, 1.001 to 1.019 at two places contains only 1.01. The tool uses browser Web Crypto randomness with rejection sampling, and unique mode samples without replacement rather than repeatedly guessing. Sorting rearranges the generated values after selection.
A practical example
To pick three different numbers from 1 through 10, set those bounds and disable duplicates. Asking for 11 unique whole numbers in that range is impossible.
A useful tip
A range from 1 to 5 contains only five unique whole numbers. To request more results, allow repeats or widen the range. Identical minimum and maximum values produce that one value when it fits the chosen precision.
Good questions. Simple answers.
Can I use negative numbers and zero?
Yes. Bounds may run from −1 billion to 1 billion. Enter decimals with a dot, without commas or scientific notation.
Is this intended for security secrets or regulated drawings?
No. It is a general number-list utility, without an audit trail or a guarantee for a specific security or regulated use. Use the dedicated Password Generator for passwords.
