Does this calculator support dual mode(have backup battery)?

I'm looking for a "solar only" (no auto-shutoff) calculator, but the description on this one says "2 AA batteries required." -- maybe seller can answer?

what are the dimensions in inches?

I use these for my Compassion Boxes (Samaritans Purse), have them already packed up, but I can assure you they are a just right size maybe approximately 3 x 5". Very solid and solar is why I buy them, so they don't need continual batteries, which these children do not have access to. That is the best I can do for you! I just noticed it says 3" x 5" 2.25 (FX-260 SolarII-SIH) This should answer your question for sure!

Does this have statistical functions?

It has the basic stats functions, such as sample and population average, standard deviation, etc. It's been decades since I studied stats, but the FX-260 SolarII has the basics stats functions, yes.

First I need a calculator that can do fractions. (Into fractions) It says it's a solar powered but product description says batteries?

This item should have the ability to calculate fractions during the SHIFT mode. This item is solar powered and does not need batteries.
