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: Using e on the BA II plus financial calculator

Hello,

To use the exponential function, **you must enter the number then press [2nd][e to the x] or [e^x] for short.**

e^(-0.1) is entered as (-)0.1 [2nd][e^x], where **(-)** is the change sign key

You will need to use extra parentheses to avoid errors.**20 - 18*( (-)0.1 [2nd][e^x] ) [=]**

The Minus sign between 20 and 18 is the regular one. The** (-) **before the 0.1 is the change sign key **(-)** or sometimes labeled** +/-**. The asterisk is the multiplication sign.

Hope it helps.

Break the problem up into smaller pieces.

There's a limit to how big a number the calculator can represent. Numbers as large as 10 times 10 to the 100 simply can't fit into the calculator. For really large numbers, calculate the mantissa and the exponent (power) separately.

For example, to calculate 2^360, first calculate 2^300: press 2 ^ 3 0 0 = and see 2.037036*10^90. Divide by 10^90 (and remember the 90): / 1 0 y^x 9 0 = and see 2.04. Multiply by 2^60: * 2 ^ 6 0 = and see 2.348543*10^18. Multiply that by the 10^90 we took out earlier by adding exponents and write down 2.348543*10^108. That number is too large to fit into the calculator but we got it by calculating the 2.348543 and the 108 separately.

The same way you raise a number to a non-fractional power, using the y^x button. For your example, press

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

Press 2 1 6 y^x 3 1/x =

The y^x button is located just above the 9 button, the 1/x button is located just above that.

The y^x button is located just above the 9 button, the 1/x button is located just above that.

$596.57 is what I get with payments occurring at the beginning of the month. Set it to handle payments at the end of the month. My calculator gives $599.55 for this case.

I'm not sure about the BA RE, but on the BA-II Plus you change the Begin/End setting by pressing 2nd [BGN] and 2nd [SET].

Work with the simple formula:
Interest = Initial * rate * time

To find the total amount, add the Initial plus the Interest, then subtract what has been paid. This will change the amount of money that will be accruing interest, though, so if there is a payment schedule you will need to repeat this calculation to get an exact number.

Error 5 indicates one of two conditions while doing a TVM calculation.

1) You tried to compute the interest rate when FV, PV, and PMT all have the same sign. Make sure cash inflows are positive and outflows are negative.

2) The LN input is not greater than zero during calculations.

The first is much more likely.

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 gave up using the Texas BA II. I used an on-line mortgage calculator for interest only. I was able to get a full printout.

I would like to learn more about the BA II and how to do this type of math on it.

Thank you
