How to calculate 24124 mod 19937 in casio fx-991Ms calculator
The MOD function simply returns the remainder that is left over after dividing the two numbers.
In this case, its possible to see quite easily that only 1×19937 can be taken from 24124 before the remainder is less than 19937. The MOD function is therefore the same as 24124 - 19937 = 4187.
In cases that are less obvious, do the division, ie 24124 ÷ 19937 = 1.210011536[34]
[The last two digits are hidden on the display but still used in subsequent calculations].
Then obtain the fractional part by subtracting 1 to give 0.210011536[34]. Then multiply the answer by 19937 to give 4187. Assuming that you haven't cleared the screen between each section of the calculation, the screen will show "Ans×19937 [=] 4187".
