I have a temperature that is displayed like this:

```auto
temperature: 1563

```

I would like it to look like this:

```auto
temperature: 15.6

```

How would I do that?

Displayed where?  
You can use a function node to

```auto
msg.temperature = Math.round(msg.temperature / 10) / 10;
return msg;

```
