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: 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.

I need to use the EE button on my BA II plus professional finanacial caluclator. I need to calculate 2.06 * 10^23 divided by 3.78 * 10^28...Help?


If you do not have the Enter Exponent key (EE) you can use the general power key marked [Y^x], the one above the [9] key. Use parentheses to enclose the (10^23) and (10^28).
Frankly, if you have to do many calculations of this kind, better buy yourself a scientific calculator.

To raise a value to a power, use the y^x key located just above the 9 key. For example, to raise 2 to the third power, press 2 y^x 3 =

Is it possible to calculate cube root or higher with BA ii plus?


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)
