I have numbers like

```auto
1.553
23
2.383
26
566

```

When I parse this with logstash, I get string value of these.

When I try to use mutate filter plugin like below;

```auto
mutate {
     convert => {
            "number_field" => "integer"
      }
}

```

It returns wrong.

I mean as an example, **2.383 as input goes 2 as output**.

My expections is below

```auto
1553
23
2383
566

```

How can i solve this ?

Thanks for answering

Use integer\_eu instead of integer.
