No, but I would rather ask: Why use alkaline batteries in the first place?

Rechargable 2500Ah NiMH batteries cost exactly the same as good alkalines and provide the voltage the calculator was designed for. The calculators can safely be used with it's charger when working at one's desk (try that with alkalines instead...). And, also import to some, one set of NiMHs outlasts 500 sets of disposable batteries.
