Scientific temperatures

Discussion thread for Scientific temperatures.

I was directed to report an issue with code execution failure. It is quite the rookie error, I forgot javascript’s function for exponents was Math.pow() and not exp(). The compiler doesn’t recognise exp() and throws this.

Error: Traceback (most recent call last):
File “/root/lovelace-engine/engine/”, line 128, in on_post

For quite a standard error, I didn’t expect such a need to report such issues to the Discourse, but I err on the side of caution and report it anyway.

Hey again @LECAGO! Thanks for reporting this. I think we were a little generous with the errors lol, but glad to know that it does work! I changed the error message slightly in case it’s an error in the code vs. an error in the website.

PS: I thought Javascript did have a Math.exp() but you’re right it’s not the function for this problem.
