This formula…

{{((Temp\<0)_(4.689_(1.486+(Temp/100))^12.3)_(18.02/(8314.3_(273.15+Temp)))_1000+(Temp\>=0)_(288.68\*(1.098+(Temp/100))^8.02)_(18.02/(8314.3_(273.15+Relative humidity)))_1000)_  
/100}}

…generates a value with a lot of decimals. I only need one. Can this be solved anyhow?

```auto
round(value[, n])

```

Rounds `value` to `n` decimals, or 0 if not specified.
