I want to calculate the absolute humidity in a room to decide about ventilation. Therefore I use calculations that require exponents for formulas as described here: https://www.wetterochs.de/wetter/feuchte.html
Unfortunately when I have a line like
val sdd = 6.1078 * 10^((7.5*temp)/(237.3+temp))
I get the error
Configuration model 'air_climate.rules' has errors, therefore ignoring it: [33,24]: no viable alternative at input '^' [35,14]: no viable alternative at input '^'
I didn’t find a description or guide about mathematics in rules, so I would be glad if somebody could give me a hint whether this is possible at all.
Thanks a lot in advance!
