# Division of complex numbers in the HP Prime

05-27-2019 06:58 AM

I'm trying to split complex numbers in HP Prime. But I am not getting the expected result. Check the image below:

The HP Prime doesn't calculate the exact result of this fraction.

How can I get the exact result?

Note: I am performing this calculation in HOME mode.

What *exactly* does 1 divided by 3 or 1/3 equal when written as a decimal? Can you write it out *exactly* for me?

Think about that question and get me a response, and I think you will discover it is the same answer. 🙂

Although I work for the HP calculator group as a head developer of the HP Prime, the views and opinions I post here are my own.

HI GabrielM8,

I've just seen that you wanted the answer in Home Mode.

In case you might have overlooked, the Home mode is for calculating approximate numbers.

So if you are trying to obtain the answers close to an exact number then you should use the Prime in CAS mode.

As can be seen from my answer above.

Hi!, @Corruptissima :

You can see, the excelent contribution, of ... Mika Heiskanen & André Schoorl ...

HP Prime port of QPI 4.3 (originally for the HP 48 series). Approximates any floating point numbers by a rational number, square root, multiple of PI, exponential or a logarithm depending on which approximation seems best.

Hi Maké,

Good to see you!

Yes, both M. Heiskanen & A. Schoorl are amazing programmers and contributed many good and valuable programs to HP 48 calculators.

You are doing a lot of contribution to helping others so hats of to you too, Maké!

See you again, Maké.

Just press the [a b/c] key to toggle through different values on the last item on the home screen.

QPI is really only for program use normally.
