Convert integer value to word

[jmgimo75]

Hello good.
I have a question with an entry reading.
I have an entry that I cannot read in word (from 0000 to 03e8) on your site I get it (from 0 to 1000)
My question is. Can I convert the input integer value to a word (WORD)?
How can I do it???

Thanks a lot

What do you mean by a word and what are you going to do with it that needs it in that form?

So essentially you want to convert a number to a hexaceimal format (less the leading 0x)?

This can be achieved in plain old JavaScript in a function node.

As you have provided nowhere near enough info, I will make assumptions:

• I am assuming msg.payload is a number
• I am assuming you want to put the result into msg.payload

msg.payload = msg.payload.toString(16).split('0x')[0].padStart(4, '0')
return msg

Proof:

I would add a small comment (and happy to hear feedback if I'm missing something):
I prefer using String() rather than .toString(). toString() generates a runtime error and aborts the message forwarding if msg.payload is undefined or null, while String() returns valid strings with the value 'undefined' or 'null' respectively.

@omrid

while String() returns valid strings with the value 'undefined' or 'null' respectively.

The issue there is you wont have a catchable error & that "string" will displayed (or store in DB or whatever the OP intends to do with it)

Of course, they may want that and your response is perfectly valid - but alas, too little info provided.
