calculation in automation

[Tiziana Pisenti]

I have the following automation:

calculation aaRaumindex= ({{issue.customfield_10201}} * {{issue.customfield_10200}}) / (({{issue.customfield_10202}} - {{issue.customfield_10211}}) * ({{issue.customfield_10201}} + {{issue.customfield_10200}}))

calculation aaRaumwirkungsgrad=0.0212 * ({{aaRaumindex}}*{{aaRaumindex}}*{{aaRaumindex}}) - 0.2225 * ({{aaRaumindex}}*{{aaRaumindex}}) + 0.7844 * {{aaRaumindex}} - 0.0074

Somehow the last calculation is not right.

The correct formel is: 

Raumindex = (Breite x Länge) / ((Deckenhöhe – Höhe Nutzebene) x (Breite+Länge))

Raumwirkungsgrad = 0.0212 * Raumindex3 - 0.2225 * Raumindex2 + 0.7844 * Raumindex - 0.0074

Lichtstrom = Beleuchtungsstärke x Fläche / (Raumwirkungsgrad x 0.72)

Here a correct calculation:

In Jira the Raumindex and Raumwirkungsgrad calculations are correct. But for the Lichtstrom the result is 620'162.078 and that is wrong. Is the automation too complex, or why does it not work?

When you are storing a value in a variable via calculation, please use the mentioned below notations.

{{#=}} {{issue.customfield_10201}} * {{issue.customfield_10200} {{/}}

Or it will be more benfiecray if you use in every calculation.

Hey,

Have you tried adding brackets where needed, to make sure that it has the correct order of operations?

Kind Regards,
