Question about Texas Instruments BA-II Plus Calculator

1 Answer

Interest conversion I'm attempting to do interest conversion on the calculator. Originally, I believe the only problem I had is that under the ICONV screen, I would enter a number for nominal interest, then a number for I/Y, and then when I would go back up to effective and hit compute, nothing would happen - I would just get all zeros. Then I looked in the manual for the calculator, and it said something about clearing the worksheet, so I did that - the 2nd key and then clr work. Now, when I go to the ICONV menu and enter a number for nominal, it doesn't stay. For example, if I go enter a number for I/Y, and go back up to nominal, my number that I entered has changed to 0. And if I go try to compute the effective, the same thing happens as before - I get 0. Any hints here? I'm taking a test with this in a couple of weeks, so if nothing else I can go buy a new one, but if it's something I'm doing it'll happen on a different calculator too.... Thanks.

Try hitting Enter after plugging in the numbers. That should make the numbers stay.

Where is iconv function for calculating effective interest rate ?

Page 24 of the attached manual shows you how to calculate the effective interest rate. I couldn't find an iconv function, but there are functions to move between the simple and effective interest rate.

Good luck,

Paul

Paypal currency conversion

Paypal along with any other bank can charge you above current listed exchange rates. They are charging what is called a currency conversion fee on top of the conversion rate. For instance, American Express will charge say 4% on top of the conversion when you spend foreign currency on their cards. MasterCard & Visa do the same thing. Even if you were to go to England tomorrow, when you bring your US dollars to have them converted in the airport the rate is always above the current spot market rate because they include a conversion fee. Sorry but you aren't due any money back and no interest, Paypal is doing nothing wrong.

There is a "c" to the lower right of my screen.

The "C" is indicating that the calculator is set to use compound interest for the odd period. To use simple interest, press STO EEX.

Trying to use unit conversion feature and can't figure out how to use the feature

Assuming you want a conversion listed on the inside of the case:

Enter the value to be converted, press SHIFT 8 to bring up the conversion screen, enter the two-digit number for the conversion, then press =.

For example, to convert 2.1 inches to centimeters (conversion 01):
2 . 1 SHIFT 8 0 1 =
and see 5.334

How to convert on casio fx-115es calculator

You have 40 possible unit conversions (20 one way and 20 the opposite way).
Each conversion operation is identified by a unique 2-digit number: for example, 01 is the conversion from inches to centimeters and 02 is the conversion from centimeters to inches.
For the whole list consult your manual or the quick reference card that is inserted in the calculator slide cover.

To convert 5cm into inches
  1. Enter the number 5
  2. Press [SHIFT][8] to activate (CONV)ersion screen
  3. You will be prompted to enter a two digit number between 01 and 40 (You must enter 01, 02,03, ...,09)
  4. In this case you enter [02] to convert cms>in
  5. and you press the [=] sign to execute the conversion.

It stands to reason that you only convert between units as directed in the table.

TI-84 has problems converting between rectangular and polar. is there a fix for this?

The conversion from rectangular to polar coordinates requires the calculation of an angle . If the angle unit that the calculator is configured for is different from the one you have in mind, you get (not erroneous results) but unexpected ones.
If the angle unit under [MODE] is radian, the angle you get in the conversion is in radians. Similarly, if the angle unit is degree, the angle obtained after coordinate conversion is in degrees.

Check your angle unit and restart your calculations.

My hp is giving me wrong principal and interest payments.

Various formulas for calculating interests exist. Make sure you are using the correct one. If a C appears on the bottom of the screen and to the right, the interests are compounded. If No C is displayed the interests are simple. That could explain the discrepancies.
