Question about dewpoint depression or is there a way to perform math operations on two webtags

[BigOkie]

Simple question here. If I take outside temp and dewpoint temp, can I use ot-dt = depression to make it work somehow in the webtags? I'm not looking to code it in php or anything, I'd just like something I could use in an api call in a hurry. If not, it's no big deal.

Thanks

Hi,

No, afaik you can't perform calculations on webtags without taking additional measures.
