Is the range inclusive of both min and max?

Yes, both endpoints are included as possible outcomes, so a range of 1 to 6 can produce 1 or 6 as well as everything between.

What happens if min and max are the same number?

The tool always returns that number, since it's the only whole number in the range.

Can I use negative numbers?

Yes, min and max can be any finite numbers, including negative ones, as long as min is less than or equal to max.

How is this different from the Random Integer Range Generator?

This tool returns exactly one integer per generation, while the Range Generator produces a whole batch of integers at once from the same kind of range.

Random Integer Generator - One Whole Number Between Min and Max

Overview

Introduction

This tool draws exactly one random whole number from within an inclusive min/max range you set.

It's the simplest possible number generator in this collection — no batch count, no decimal mode, just a single integer and a Regenerate button to draw again.

What Is Random Integer Generator?

A single-value random integer generator that samples uniformly across every whole number between min and max, both endpoints included.

The underlying math is the same discrete uniform distribution used by dice, lottery draws, and coin flips generalized to any range.

How Random Integer Generator Works

Min is rounded up and max is rounded down to the nearest whole numbers, then the tool picks uniformly among every integer in that closed interval using Math.random().

Each click of Regenerate re-runs the draw independently, so consecutive results can repeat — this models sampling with replacement, not a shuffled draw without repeats.

When To Use Random Integer Generator

Use it whenever you need exactly one random whole number — picking a winning ticket, deciding a tie-break, or choosing a random step count.

For a list of several random integers at once, use the Random Integer Range Generator instead, which is built for batch output.

Often used alongside Random Integer Range Generator, Random Number Generator and Random Even Number Generator.

Features

Advantages

Minimal, focused interface with just min, max, and Regenerate — nothing to configure incorrectly.
Instant client-side generation with no network delay.
Handles negative ranges and single-value ranges (min equal to max) correctly.

Limitations

Not cryptographically secure — uses Math.random(), unsuitable for anything security-sensitive.
Only ever returns one value per generation; there's no built-in way to guarantee the next draw differs from the last.

Examples

A dice-like roll

Input

(no input; generated from settings: min 1, max 6)

Output

One whole number sampled uniformly from 1 through 6.

A negative-range draw

Input

(no input; generated from settings: min -10, max 10)

Output

-3

Negative and positive integers are equally likely across the range.

Best Practices & Notes

Best Practices

Set min and max as close as possible to the actual range you need to avoid mentally discarding out-of-scope values.
Use the Regenerate button rather than reloading the page to draw a fresh value.

Developer Notes

Min/max are normalized with Math.ceil/Math.floor before sampling, so a fractional range like [2.2, 2.8] correctly reports an error since no whole number falls inside it.

Random Integer Generator Use Cases

Breaking a tie between two options by picking 1 or 2
Choosing a random row or item index for manual spot-checking
Picking a random step size or delay value for a script

Common Mistakes

Assuming this tool remembers previous draws and avoids repeats — it doesn't, each draw is independent.
Using a range with no whole numbers in it, like [1.1, 1.9], and being confused by the resulting error.

Tips

If you need several values at once, switch to the Random Integer Range Generator instead of clicking Regenerate repeatedly.
Negative ranges work fine for offset or delta calculations.
