Question about Texas Instruments TI 30XIIS Scientific Calculator

# I don't know if maybe my calculator has a function turned on that rounds the answer to a whole number? But here is an example: 106 x 6.32 = 670 according to my calculator, which is wrong. The real answer is 669.92. My division does the same thing as well: 106/6.32 = 17 according to my calculator. Real answer is 16.7721519. Is there a key I need to press in order to fix this or is my calculator just busted?

Your calculator is set to display no digits after the decimal point. To change this, you have two options: press 2nd [SCI/ENG] then select "FLO" for floating decimal or press 2nd [FIX] then select the desired number of digits after the decimal point (or F for floating).

### How to calculate mode with caso fx-991ES

MOD simply calculates the remainder that is left over after dividing by the MOD parameter.
For example, 10MOD7 = 3 since you can only divide 7 into 10 once, leaving a remainder of 3.
For larger numbers, eg 389487MOD31 you start by dividing 389487 by 31, which gives 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD calculation has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculators working capacity.
An alternative method is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

### How to find remainder as a solution in CASIO fx991ES

Finding the remainder from a division calculation is often referred to as using the MOD function, though this isn't available directly on the fx-991ES.
To obtain the remainder, for example when dividing 10 by 7, you can only divide 7 into 10 once, leaving a remainder of 3.
For larger numbers, eg when dividing 389487 by 31 (equivalent to 389487MOD31) the division gives an answer of 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD or remainder calculation involving integers has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculator's working capacity.
An alternative method which avoids the rounding of the fractional part is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

### Large factorials ti84

The TI-84 is limited to numbers with at most twelve significant digits.

If you must know the EXACT value of 16!, try this. Calculate 14!. Note the two zeroes at the end. Strip them off by dividing by 100 and remember the two zeroes. Multiply by 15. Strip off the last zero by dividing by 10 and remember that we've now stripped off three zeroes. Multiply by 16. Add the three zeroes at the end to get a fourteen-digit number.

In this particular case the result is exactly what you get by using the FACT function. That's also true for 17!, but it breaks down past that because 18! has more than twelve significant digits.

The whole point of the calculator is to allow you to do calculations with a reasonable degree of accuracy, as opposed to exactly. You'll notice that it can't do a simple operation like dividing 1 by 3 and produce an EXACT answer---only a twelve-digit approximation.

### How to calculate a percentage - whole numbers

Say you want to know what percent x is of y (or To find out x is what percent of y).
We take x / y and times 100. Depending on what x and y are this might not always be a whole number,
we could round the number off to a whole number. An example: 81 is what percent of 135? To solve this
take (81 / 135) * 100 = (0.6) * 100 = 60 percent.
