Hello,  
I want to get rid of the decimals.  
My function node is like this:

```auto
gas = parseFloat(msg.payload.svalue1);
msg.payload = gas;
msg.topic = "gas";
return msg;

```

The outcome data is like:  
gas : msg.payload : number  
2437.604

or sometimes 2450.50

or sometimes 2730.3

I only want to use the whole numbers (integers).

How can i change the function code to only get the numbers before the decimal point?

You can use `toFixed` if you want a fixed number of DP's. Just be aware that it turns the number into text though.

I would do a google search using 'javascript how to strip decimals from number'

Here is an example in a `function` node

```auto
msg.payload = Math.trunc(msg.payload)
return msg;

```

well you could just use `parseInt` instead of paareFloat...  
but maybe you want to round to nearest integer instead in which case you could use `Math.round(gas)`.

Thank you all. All sugestions were helpfull. Finanaly I used the Math.round code and it is working very well.
