How the Dec to hex? And the node can show warn or errer information?

@jlian168

5000(Dec)=1388(Hex)

Now is ["1388","13","88"]
I hope is [1388,13,88]

What do you want to see in your array for the input 4990?

Dear Colin :

Yeah, sorry All.

Hex is ["1388","13","88"]
Dec is [5000, 19, 136]

I hope is 5000=[50, 00] in array.
its one 16bits to two 8bits...
So what kind of suggest is better?

Thank u.

Just for info
msg.payload = Number("0x"+"138a");

if you add "0x" to the hex string it can be converted back to a number
