# ABS

> The ABS function calculates the absolute value of a number and works across multiple YiDA scenarios, including Forms, workflow design, and integration & automation. Call it using the format ABS(number), where number is a required parameter. This function returns an absolute value of the Numerical type.

## Supported Product Scenarios

The ABS function is supported in the following YiDA scenarios:

* Form (main table field)
* Form (business association rules)
* Form (validation)
* workflow design (validation rules)
* workflow design (association action)
* integration & automation
* Workflow - Node
* Connector

## Format

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
ABS(number)
```
