Complex numbers calculation

[xavier.vanderhaeghe]

Hello everyone,

I have different problems with complex calcultions with my HP Prime.

I know how to use RE(), IM(), ABS() for complex numbers that are defined by numbers, like 3+2*i. I also know how to sotck them into Z0, Z1 etc.

But I would want to to the same for complex numbers that are defined by characters, like a+b*i.

Could someone help me with that?

In the picture, you will see that I tried to stock and to find the real part of a complex number, but it doesn't work.

The idea is that I put my complex number in my HP Prime and that I get its real part, imaginary part and absolute value.

Thank you in advance for your help
