How does the battery get changed?

The one I have recharges itself with any light it gets. It charges on sunlight, or the lights in your house. I've had one of these for years, and I honestly never had to change the batteries. Light of any kind is all it needs.

How do you change the number of digits after the decimal?

Change the decimal settings to F for float

How to Calculate adding a percentage? I want to do for example 100 + 10% and the answer should be 110 but shows 111.1111111

To get number plus 10% multiply the number times itself and the percentage you want. Like this--- - hit 100 x 1.10 = for 120%---- hit 100 x 1.20 = The '1' in the "1.20" represents the number itself being multiplied. The number to the right of the decimal is the percentage increase you want. I hope that helps. You do not have to use the percentage key
