For my internship I have to make sure I can filter numbers out of a piece of string inside of an Array (being: .nl per month: 0,83, etc).

For that I used the following code: `$nlMonth = (int) filter_var($fileLines[1], FILTER_SANITIZE_NUMBER_INT);`

The result I get is 83, while it needs to be 0,83. Does anyone know any solution to this?
