I have Written a code in function ( Multiple output ) as below which receives the data through modbus

var msg0 = {payload:(msg.payload[0]\<\<16) + msg.payload[1]};  
var msg1 = {payload:(msg.payload[2]\<\<16) + msg.payload[3]};  
return [msg0,msg1];

i'm getting msg0 output of function as as 4145 but i required 41.45. Kindly suggest what code to be written to get the expected output as 41.45.

Divide it by 100

```auto
var msg0 = {payload: ((msg.payload[0]<<16) + msg.payload[1]) / 100};
var msg1 = {payload: ((msg.payload[2]<<16) + msg.payload[3]) / 100};
return [msg0,msg1];

```

At a guess, you are working with modbus data? If so, there is a contrib node designed to help with all the 16 bit / 32 bit / float / masking / bit shifting etc - makes this a trivial and low code experience - `node-red-contrib-buffer-parser`

can you share the values coming out of the modbus node **AND** the values you expect them to become?

(add a debug node set to `show complete message` & use the copy value button to grab a copy of the entire message)

Hi could you try again please. Set the debug to show complete message & use the copy value button...
