Calculate remainder on Casio fx-991 ES Calculator Is it possible or not to calculate remainder through use of Casio fx-991 ES Calculator. If possible then how
for example :- I have to calculate remainder of 2345763534 rem 24 and other media except calculator is forbidden. If this isn't possible through calculator then any short cut method are also appreciated.
 A: Use the calculator to find
$$
2345763534/ 24 = 97740147.25
$$
That is the remainder is
$$
2345763534 - 24\cdot 97740147 = \dots
$$
A: I thought that I'd add the answer I found here as I found it more helpful than the current answer.

I am afraid that this calculator don't have any modulo function. However there is quite simple way how to count modulo using display mode ab/c (instead of traditional d/c).
How to switch display mode to ab/c:
  
  
*
  
*go to settings (Shift + mode)
  
*press arrow down (to view more settings)
  
*select "ab/c" (number 1).
  
  
  Then do your calculation (in comp mode), like 50 / 3 and you will see 16 2/3 thus mod is 2 or try 54 / 7 which is 7 5/7 (mod is 5).
  If you don't see any fraction then mod is 0 like 50 / 5 is 10.
The remainder fraction is shown in reduced form, so 60 / 8 will result in 7 1/2. Remainder is 1/2 which is 4/8 and mod is 4.

EDIT: Note that this doesn't work for everything. Especially if the fraction can be simplified (e.g. 6 mod 4). But I still believe it's a useful shortcut to keep in mind, just make sure the fraction has the modulus as the denominator. 
A: Another way of doing this is with the BASE-N mode. In this mode, the divisions are made as integer calculations in a programming language A/B, so the A%B (A mod B) operation can be obtained as:

A−B(A÷B)



*

*Pros: This works on any basis (including 10) and for negative numbers.

*Cons: Since the CALC mode is not allowed into the BASE-N mode, A and B values should be previously STOred.

A: I think jdeo's method works for negative integers aswell:
-7 mod 4
-7/4=-1.75
Next step is make a positive fraction that is less than 1
-1.75+2=0.25
Then 0.25*4=1
Therefore -7 mod 4 = 1
Please do let me know if this is wrong :)
Thanks 
A: Disclaimer: This is a highly specific answer for calculators of the casio family that support Pol and Rec functions, which convert cartesian coordinates to polar and vice versa.
Suppose you want to know what A mod B is, you can do the following then:
Pol(-Rec(1/(2π) , 2π×A/B), Y)(π - Y)B

Hereby, Y is an arbitrary constant, e.g. 1.2345, 1337 or -42. It doesn't matter, because the Rec function will overwrite the value.
