Hello,

I try to publish on a screen my electricity production but with the sensor that i use, i have on the screen a too big number with 2 decimals, for example 1835,48 W. I would like to split the decimals to show on the screen only 1835 W. I don't know how to do.. Does anybody know how i have to edit my script ?

var value = msg.payload;  
var unit = msg.data.attributes.unit\_of\_measurement;  
[//msg.payload](https://msg.payload) = price;

msg.payload = {  
// "text": value + ' W',  
"text": value + ' ' + unit,  
"icon": 42453,  
"duration": 4,  
"repeat": 1,  
"pushIcon": 3  
};

node.status({ fill: 'green', shape: 'ring', text: value + ' ' + unit});

return msg;

I'm sure there are different ways of doing this but this is the way I do it. I add this line right before the return msg;  
msg.payload = Math.trunc(msg.payload);

Could also use this to round down...  
`let value = Math.floor(msg.payload);`

Or this to round up...  
`let value = Math.ceil(msg.payload);`

Or this to round to nearest integer...  
`let value = Math.round(msg.payload);`

Or this to convert a string to an integer, also works on numbers...  
`let value = parseInt(msg.payload);`

Also see this previous post -

> If for example, you are displaying the value in a dashboard text node, you can always use angular filters to format the number. Adding {{msg.payload | number:1}} mph to the text node value format box will format a msg.payload from 18.31158 to 18.3 mph
