Lets say I have an account field called euro-budget, and I have a content type exchange rate including the field usd-value" which import the USD exchange rate every 2 hours. In the view which displays all users including the field euro-budget. I want to have a calculated field which multiplies the field euro-budget with the latest usd-value field. What is the easiest way to do this? I already tried Views PHP but it is somehow not compatible with the latest Drupal 8 version.
