# toFloat

> Tries to coerce value into a float (32-bit floating point vaule).

**This function is used by Ignition's Expression language.**.

## Description
Tries to coerce value into a float (32-bit floating point vaule). If value is a number, the conversion is direct. If value is a string, it is parsed to see if it represents a float. If not, type casting fails.

## Syntax
`toFloat(value[, failover])`

- Parameters

    - object **value** - The value to type cast.

object failover - Optional. The failover value if type casting fails.

- Results

    - Float - The value type cast as a float.

## Examples
```python title="Code Snippet"
toFloat("38.772") //returns 38.772
```
```python title="Code Snippet"
toFloat({Root Container.TextField.text}, 0.0) //returns the value in the text box as a float, or 0.0 if the value doesn't represent an number.
```
