Division of complex numbers in the HP Prime

HP Prime
Other

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. 🙂

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.

Kind Regards !.
Have a nice day !.

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.
