Hi

I was trying to dump out onewire IDs in Hex. I took the device ID
from ow.search and called toString(16). I think this caused Espurino
to crash.... the device ID was a huge negative number when normally
printed.

Sorry for not quoting the number itself.

P.S. Where should I post bug reports if not here?

Hi. Thanks for letting me know... It's best to post on the issue tracker: http://www.github.com/espruino/Espruino/issues

Do you want to do it - or I can.
```
(-1000000000000000000).toString(16) // works
(-10000000000000000000).toString(16) // crashes
(8446744073709551616).toString(16) // crashes
```
Interestingly this appears to be the point at which the number rolls over and becomes positive - so it's large numbers rather than just negatives.

Ok, fixed now - it'll be in 1v61

Thanks - I guess that means I don't have to post it as an issue :)

Nope, that's fine ;)

Next release should be a good one - there are over 15 fixes in it now - and counting :)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
