# supportExpressions

> Indicates whether the field supports expressions that can be evaluated into a value.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine.UIElements](/engine/6000.5/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule

```csharp
public bool supportExpressions { get; set; }
```

### Remarks

Expressions are mathematical or logical constructs, such as "1+1" or "5"2", which can be processed to produce a result. When this property is enabled, the field accepts additional characters required for expressions (e.g., '+', '-', '"', '/', etc.), expanding its functionality beyond the typical restrictions of a text field that might otherwise only allow digits.
