In city production view, viewing production reads how many turns it takes to complete, e.g. build scout 5 turns. But in gold purchase view, it shows the price instead, e.g. 70 gold. While this is certainly critical, I'd also like to see the number of turns until the purchase can be made, in the form of:
I always have to do this on a calculator by hand whenever I need to compare whether it's faster to produce or buy something.
Code:
ceil((purchase_cost - current_gold) / gpt)
