Hi.
It sounds like you have lost all of the programming from the machine. Have you had the machine regularly serviced? If the internal battery hasn't been changed in the last 4 or 5 years, then you have probably lost everything. Since these machines are so old, it won't really be worth spending any money or time on it. Most parts are very worn in this model now, so you will soon be looking at print head or motor failure. There may be a lot of programming to go back in, and it would need to be stripped down for battery rplacement. You would be better off to buy something newer for the same price as the repair.

A mod B in Casio fx-115MS How to get an m mod n (ie to calculate modulo of a number)


It's a bit convoluted, and it only works for integers, but here's one way. Press MODE 4 to switch to BASE-N (integer) mode. If the screen doesn't read "Dec" then press the x^2 key. Now, to calculate m mod n, calculate m-m/n*n. No shortcuts, no rearranging. That's m minus m divided by n times n. You have to enter both numbers twice, but you will get the modulus.

Press MODE 1 to return to your previously scheduled calculations.

Can i do statistics on the casio fx-115 es? and how can i use it?


Yes and here is how to do 1-var statistics and 2-var statistics. Please read the whole post. I assume you know the theory. I will show you the key strokes

For 1-Var statistics
Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.
Enter a number and press [=]. Cursor jumps to second number to enter.
Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.
Press [AC] key to clear the screen.
Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.
Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.
To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics
To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

How to get a Casio out of rounding mode


Press the MODE key a certain number of times, until you reach a screen that displays FIX SCI NORM and numbers 1, 2, and 3 under them. Press 1 key to select the FIX display format, then enter a number between 0 and 9 to set the number of decimal digits you want to keep in your result. In your case the calculator is already rounding so you should select a reasonable number of digits say 2 to 3.
MODE (a certain number of times ....) 1 (FIX) 3 will keep three decimal digits in the results.
