# Number (Integer) Fields

Integer fields are optimized for holding whole numbers. They are essential when you need to count items or denote a rank, storing values like 5. These fields use numeric inputs and allow for customization by setting minimum and maximum value limits, providing control over the range of acceptable inputs.

**Technical Limits**: Integer fields are limited by JavaScript's maximum safe integer value of **9,007,199,254,740,991** (approximately 9 quadrillion). Values larger than this limit may not be handled correctly and could cause validation errors.
{% endhint %}

## Integer Number Field Formats

* **Default** By default, the integer number field shows a formatted number such as 1,234,000
* **Currency** Display the number as a currency, and choose the specific currency symbol. For example: £1,234,000
* **Rating** Display the number as a star rating. You can configure how many stars should be displayed (the max value)
* **Unformatted** This displays the number without formatting, such as 1234000. This is useful for numbers that aren't really numbers, like Postcodes, or Object IDs
* **Slider** Displays the number as a slider when used as an input, and a visually similar progress bar otherwise. Configure the min, max, and step value of the slider.

{% hint style="info" %}
**Numbers** are displayed based on your browser settings
{% endhint %}

## Integer Field Options

* **Allow negative numbers** Depending on the format chosen above, you can optionally enable or disable the use of negative numbers in the field, which will be enforced in all forms
* **Prefix** Configure a prefix for your numbers, such as `USD 123,000`
* **Suffix** Configure a suffix to your numbers, such as `12,000 Books`

## Use Cases

Integer fields are perfect for:

* Counting items (inventory, users, etc.)
* Rankings and scores
* Quantities and amounts
* Ratings and reviews
* IDs and reference numbers (using unformatted display)
* Progress tracking (using slider format)

## Best Practices

* Use Currency format for monetary values without decimals
* Use Rating format for user feedback and scoring systems
* Use Slider format for values within a specific range
* Set appropriate min/max limits to prevent invalid data entry
* Use prefixes and suffixes to provide context (e.g., "USD" prefix, "items" suffix)
