```
  add_field => {"geoip.location" => ["%{longitude}","%{latitude}"]}
  convert => { "geoip.location" => "float" }
}

```

I'm not sure if these directives are necessarily processed in order. I'd try splitting this in two mutate filters (one with `add_field` and one with `convert`) just to make sure the field is added before we attempt to convert its type.
