## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/random-number-generator/?min=1&max=100&count=1&allowDuplicates=1&seed=askcalculators

## Inputs
- min: Min; type=number; optional; default=1
- max: Max; type=number; optional; default=100
- count: Quantity; type=number; optional; default=1
- allowDuplicates: Allow Duplicates; type=checkbox; optional; default=true
- seed: Seed; type=text; required; default=askcalculators

## Outputs
- result: Result; format=text; primary

## Formula
A seeded pseudorandom sequence maps uniformly to the inclusive integer range; unique mode samples without replacement.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
