SOURCE: No decimal display on TI BA-II calculator

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][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

SOURCE: is it possible to calculate cube root or higher

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.

it gives the cube the 4th power, 5th, 6th, etc.

If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.

When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

SOURCE: how to you chage from 2 decimals to 4 on the BA II...

By default the BAII Plus displays only two decimal places. This is not enough. Personally, I like to see five decimal places, but you may prefer some other number. To change the display, press the 2nd key, then the decimal point key, and, when prompted, enter the number of digits you would like to see displayed. You must then press the Enter key to lock in your choice. I would press 2nd, ., 5, Enter to display 5 decimal places. Now press 2nd, CPT to return to a blank screen. Problem solved.

One other adjustment is important. The BAII Plus comes from the factory set to assume monthly compounding. That's fine, I suppose, but its better to set it to assume annual compounding and then make manual adjustments when you enter numbers. Why? Well, the compounding assumption is hidden from view and in my experience people tend to forget to set it to the correct assumption. Of course, most people don't recognize a wrong answer when they get one, so they blithely forge ahead. To fix this problem press 2nd then I/Y and enter 1 when prompted. Now press Enter and then 2nd, CPT to return to a blank screen. Problem solved.

SOURCE: where is the exponent key on the ba-ii plus

If you mean exponentiation (natural antilogarithm): 2nd e^x (e^x is just to the left of the 7 key).

If you want general powers: y^x (just above the 9 key).

If you want 10^x (common antilogarithm) or simply an [enter exponent] key, there are no keys for those. You'll just have to raise 10 to the desired exponent.

Here it is.

The BA-II Plus is designed for financial applications. It does not do fractions, as do some calculators intended for school use.

Sorry if that wasn't the answer you wanted to see, but there it is.

Hello,

It seems to me that you are omitting a step: see screen capture from manual (step 4). Hope it helps.
