Re: how to assign values to complex constants

I want to declare a complex constant in gpc like the following, non working example:

const I : complex = (0.0, 1.0);

You can declare this in Extended Pascal:

const I = cmplx (0.0, 1.0);

I have not found any example how to do this in the list archive or in the manual.

The page titled "Complex Number Operations" in the GPC manual gives an example of the "cmplx" function.

Is there a possibility to assign real values only to the real or imaginary parts of a variable especially to a function return value like in the following non working, sensless example:

function add(a,b: complex):complex; begin add.re := re(a) + re(b); add.im := im(a) + im(b); end;

Again in Extended Pascal:

function add (a, b: complex): complex; begin add := cmplx (re (a) + re (b), im (a) + im (b)) end;
