Hello everyone,

Does anyone know a solution?  
I have a number from a calculation and would like to make a hexadecimal of it, which I can send to my phone for my work.  
Here we use these codes to log in.  
Now I have to calculate it every day and would like to have it sent automatically every day.  
Would this be possible with Math.js?

I hope someone knows a solution.

Not sure if you can use JS code, but if so:

```auto
number.toString(16)

```

Ive just moved your thread into the developer forum, wouldnt want to scare people with talk of Hexadecimals or math.

</div>

Are there any more options within Homey?

Because through the Number. toString(16) can’t do it because Homey doesn’t recognize this option.

Am I doing something wrong or can this denomination not be in Math. js?

There doesn’t seem to be a function or option in Math.js to convert a number to a hexadecimal string ☹

I expect it to be possible with Homeyscript.  
Just call the script with the value and set a string variable with the hex value.
