Hello pascal gurus, I want to declare a complex constant in gpc like the following, non working example: const I : complex = (0.0, 1.0); I have not found any example how to do this in the list archive or in the manual. Another question concerning the same subject: 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; Any Idea?
