It seemed there is no Modulo function in fx-100MS. But Mod is just the remainder of a division operator.

So if you have A mod B = C, divide A by B, subract the remaining whole number, and multiply it by B to get C.

Example:

7 mod 4 = 3

In the Calculator:

7 / 4 = 1.75, then 1.75 - 1 = 0.75. Then 0.75 x 4 = 3

I couldn't find the manual for your JF-100MS but I have a Casio FX series calculator that, like yours, is solar + battery backup. On the back of the calculator there should be a small door or coverplate with a tiny screw. If you remove the screw the cover should come off and you can then access the button cell battery for replacement.
