Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][5][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

Rounding nearest


Set the display to 2 decimal places then use the [RND] function. See how the manual describes the Round operation.

23101423-rvrejqbjq4zuw4cbinsyjvsy-5-0.png Brief example:
01- 42 2 [f][2]
02- 42 14 [f][RND]
03- 42 9 [f][9]
The above program takes the number displayed and rounds to 2 decimal places (nearest 100th), then displays all decimal places.
If you entered 2.876 and ran the program, it would display 2.880000000.

Casio fx-82ms calculator does not give me an answer when i use the percentage button . example if i type 0.25/ 100% i get 0.25 instead of the right answer 25


Here is a sample of the percentage calculations that the calculator can perform. You will not see among them the conversion from decimals to percentages.
To convert from decimals to percents move the decimal mark 2 places to the right and append the % sign.
To convert from percents to decimals, move the decimal mark 2 places to the left.

When I divide the answer is in fraction form not decimal form how do i get it back


There are two options.

1) Whenever you want the answer in decimal form, place a decimal after at least one of the numbers.
For example: instead of using (1/2) use (1/2.)

2) Press the "Mode" button. Scroll down the list that appears until you find "Exact/Approx". If you set it to "Approximate", then it will always give the answer in decimal form. If you set it to "Exact", it will give the answer in fraction form.

Show two decimal places


Input the following and try:
  1. Press 2ndF and . the point button. This changes the screen to FIX DEG
  2. Press 2ndF +/- 2 Answer shown is to 2 dec. pl.
  3. If you want it to 5 decimal places, Press 2ndF +/- 5 answer shown is to 5 d.p. and so on
For normal, just take calculator out of FIX so just DEG shows.

Couldn't find you a YouTube video, so text will have to do.

I Cant get the Correct Answers!


If you're sure the answer isn't really 1.007, check to see if the calculator is in fixed mode. You can change it to scientific notation(that'll give you lots of digits past the decimal place, or I prefer engineering, which is scientific except all powers of ten are in multiples of three).
