Delete the decimals

[MaxSchaaper]

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

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.

Number.prototype.toFixed() - JavaScript | MDN (mozilla.org)

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

Here is an example in a function node

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.
