Q: 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?

Q: 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!

Q: 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.

Q: 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.

Extremely Handy. I would buy again if needed

I love the fact that this calculator is solar powered. Since you are not likely to use this in the dark it is very convenient to never have to be concerned about whether or not the battery is charged. i have had one of these for quite a few years and it has never failed yet. The only drawback for me is that I used calculators from HP with Reverse Polish Notation rather than algebraic entry for over 40 years and it takes a lot of getting used to. But I know most people don't have that issue so this is a really good calculator for not much money.

A good little basic (scientific) calculator.

I hate using awful cellphone calculators- this real calculator does the job. The fractions function is very helpful for construction projects.The price is low enough I bought two- one for the house, the other for the shop.
