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: 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: Hi is there a function for finding the cubed

You can calculate any root by raising to the reciprocal. For example, to calculate the cube root of 125, press 1 2 5 y^x 3 1/x =

To calculate the fourth root of 16, press 1 6 y^x 4 1/x =

The y^x key is just above the 9 key. The 1/x key is just above that.

The TI BA-II Executive Business Analyst (maybe not your model) has a key labeled FIX. It is in the middle of the topmost row of keys. Press the FIX key followed by the number of decimal digits you want.

25 = 23e^x

25/23 = e^x

ln 25/23 = x

Press 2 5 / 2 3 = LN

25/23 = e^x

ln 25/23 = x

Press 2 5 / 2 3 = LN

The BA II+ does not have a key for the common logarithm function. You can calculate the common log of a number by calculating its natural log and then dividing by the natural log of 10.

log10(x) = ln(x)/ln(10)

The same procedure works for logarithms to any base.

log10(x) = ln(x)/ln(10)

The same procedure works for logarithms to any base.

I do not see a function for that on the calculator when i look at the layout. you will most likely have to put them in by hand.

(1/4 = .25 etc.) ant then convert them back for the answers.

To calculate the natural logarithm of the value in the display, just press the LN button. If you need the common (base-10) logarithm, compute it as ln(x)/ln(10). That is, divide the natural logarithm of the value divided by the natural logarithm of ten.

The calculator has 10 memories (0 to 9)

To store a number (13) in memory 6 type 13 [STO] 6

To erase the content of memory 6 (M6) store 0 in int: 0 [STO] 6

To recall the content of memory location M7 press [RCL]7

To operate on the content of memory location M5 the syntax is [STO] [Op] 5, where [Op] is the operation symbol [+], [-],[x], [/] [y^x]

Ex: to raise the content of memory location 4 to the power of the displayed value, you press [STO][Y^x] 4

To clear all 10 memory locations

press [2nd][MEM][2nd][CLR WORK]

In short, although you do not have the keys you are accustomed to, you have a lot more. And please do not blame me if you feel disappointed.
