Question about HP 10bII Calculator

1 Answer

The numbers in the display are half there, not complete

I have the HP 10BII Financial calculator. The problem is that some of the numbers don't show up. For example when I input 8's across the screen it looks like this:


In those two places part of the 8 is missing. I also tried putting in brand new batteries just to make sure that low batteries wasn't the problem.

How do I stop the calculator from rounding my answers to the nearest integer?

It is on page 30 of the attached manual. It seems you have to set the number of decimals as a default. If you want to display all digits, you can use DISP followed by a period.

Good luck,

Determinants of matrix

First of all, the HP 10bII is a financial calculator and does not handle matrices. For all other calculators, you must first create a square matrix, using the Matrix editor. Then you look for the command that calculates the determinant. The syntax will look something like this
det (Mat A) (Enter/=/EXE)

What is CPT on TI Calculator

"ComPuTe". On TI financial calculators you have to press the CPT button before pressing the button for the value you're solving for. (N, I, PV, PMT, or FV). On an HP calculator, you just press the N-I-PV-PMT-FV button without making any entry in order to solve for the desired value.

HP10BII+ CALCULATING THE GEOMETRIC MEAN, WHEN I HIT yX it says pend and won't calculate?

When an HP calculator displays pend(ing) it is waiting for the user to complete the command. From what I understand you are raising some number to a power. You enter the number (base) you press a shift key of some sort then the [Y^x] and the calculator displays pend. It is waiting for you to enter the exponent.

Where is the CPT key on the HPb11 Financial calculator?

There isn't one. Unlike calculators from other makers, the 17bII knows whether you've just input a number or not. Simply press the desired item without entering a number to calculate it.

For example, if the book says to press CPT then PMT to compute the payment, simply press the PMT key on the 17bII.

Hi: I bought a HP 10bii Financial Calculator. I find it difficult to get a correct answer... For an easy example, I try to find the future value of $100 today after 3 years with an annual interest rate...

What you've done is calculate the future value after 3 months, not 3 years.

Press 1 SHIFT [P/YR] to set the payments per year to one. Now the FV key should give you 115.76

I have a HP 10bII financial calculator. I read that CPT does not apply to this calculator but my numbers are off. Is this correct or am I missing a step on my calculator? Does CPT apply or not?

You can use the I/YR key on the top row to enter/calculate the interest rate.

We can't tell whether your numbers are correct or not without seeing them. Could you post the problem?

Hi, my 10BII suddenly shows 0,0000000... in the window, and even when I type in new figures they end in ,00000.... The calculator has shut off and when I turn it on again there's the comma. This wasn't...

To change the number of digits displayed after the radix mark (decimal point), press SHIFT DISP and then the number you want.

To switch the radix mark between the US and European modes, press SHIFT ./, (the key in the center of the bottom row).
