# Numbers schema example

This schema example shows how to define `integer` and `number` properties and apply validation using the minimum, maximum, and multipleOf keywords to constrain user input. It also demonstrates the use of UI components, including a slider and a dropdown with labels, along with example component parameters.

> **Note:** In Dynamic Content, integers must be whole numbers. For example, 1.0 is not a valid integer.

The `exclusiveMaximum` and `exclusiveMinimum` validation keywords are not currently supported.

## Pre-requisites

This is a self contained schema that uses standard JSON Schema property types and validations.

## How to use

You can change the validation of each property to meet your own requirements.
