How The Generator Works

Decimal mode generates a random unit value in the usual [0, 1) interval and scales it into your chosen range.

Integer mode uses rejection sampling across the inclusive whole-number range so each available integer keeps an even chance, while decimal mode rounds the display to the precision you request.

Quick Examples

Integer mode is useful for counts, IDs, scores, and simple simulations.
Decimal mode is useful for prices, measurements, percentages, and probabilities.
A 0 to 1 range is a handy default for normalized sample values.
Batch generation is useful when you need several numbers with the same settings.

Frequently Asked Questions

What is the difference between this and the integer-only tools?

This tool combines both integer and decimal generation in one place, while the integer-specific tools focus on inclusive whole-number ranges.

Can numbers repeat?

Yes. Each value is generated independently, so duplicates are possible.

Why disable decimal places in integer mode?

Whole-number output does not need fractional precision, so the control is only relevant in decimal mode.

What can I use random numbers for?

They are useful for fixtures, demos, mock forms, simulations, tests, and placeholder datasets.

Useful Notes

One flexible generator can be more convenient than switching between several narrower tools.

Integer mode is best when every result must be a whole number.

Decimal mode is better when ranges and precision matter more than discrete steps.
