Probably because it’s not a particularly common real world need. Have you ever found yourself grasping for a multiply command in a cache?



No. But I don't often work on databases so I don't find myself grasping for any commands in a cache. It's hard to imagine that if there's a use case for adding a delta there's not also a use case for multiply by constant. But I'm not familiar with the market so maybe I'm wrong.


You add a delta in any situation where you want to track "how many" of something. (Page views, for example).

I can't immediately imagine when you would want to multiply.


The one I can think of is tuning circuit breakers so that failures are additive but successes decrease more multiplicatively/exponentially, which helps with fast recovery.

That’s more dividing than multiplying though
