Hi,

I am using logstash to convert below two strings into integer and then converting integer to milliseconds.

i have nginx logs with below values

```
request_time="0.051" 
response_time="0.027"

```

first i am converting them into float

```
  mutate {
    convert => ["request_time", "float"]
    convert => ["response_time", "float"]
  }

```

and them am trying to convert them into milliseconds with below method, but am getting zero printing in the kibana

```
ruby {
  code => "event.set('request_time', event.get('request_time').to_i * 1000)"
}

```

The .to\_i will round them down to zero, I think. Does it work if you use this?

```
(event.get('request_time') * 1000.0).to_i
```

Thats works, thanks for suggestion.

i have different issue while adding 2 strings into condition like below.

```
ruby {
code => "event.set('request_time', event.get('request_time') * 1000.0).to_i"
code => "event.set('response_time', event.get('response_time') * 1000.0).to_i"
}

```

is this correct format ?

Not sure if that works or if one code option overwrites the other. I would use

```
ruby {
    code => "
        event.set('request_time', event.get('request_time') * 1000.0).to_i
        event.set('response_time', event.get('response_time') * 1000.0).to_i
    "
}
```
