### Convert an array of integers to floats

```js
import "experimental/array"

arr = [12, 24, 36, 48]

array.toFloat(arr: arr)// Returns [12.0, 24.0, 36.0, 48.0]


```


### Convert an array of strings to floats

```js
import "experimental/array"

arr = ["12", "1.23e+4", "NaN", "24.2"]

array.toFloat(arr: arr)// Returns [12.0, 1.2300, NaN, 24.2]
