Hello. If one of my automated actions is to update a number field, can I make it Calculate the update? IE (Current Field Value) minus (some other value) and put that newly calculated value in the field?
Unfortunately, automations can’t currently perform calculations. They also can’t perform conditional statements, although you didn’t ask about that.
If you could make your desired value the result of a formula in a formula field, then you could update the number field based on the formula field.
One interesting thing to note is that the automation platform Integromat DOES allow you to perform math & other transformational functions on your data.
