You can use a structure and then have two parts to the structure .. the real part and the imaginary part

Mystruct is Structure
realpart is real
imagpart is real
END

Num1 is Mystruct
Num2 is Mystruct

Num1.realpart = 76.8
Num1.imagpart = 24.0

Num2.realpart = 65.9
Num2.imagpart = 11.23

myresult is mystruct = ComplexAdd(Num1, Num2)

PROCEDURE ComplexAdd (N1 is Mystruct , N2 is Mystruct) : Mystruct
ComplexResult is Mystruct
ComplexResult.realpart = N1.realpart + N2.realpart
ComplexResult.imagpart = N1.imagpart + N2.imagpart
RESULT ComplexResult

Isn't the procedure a bit ambiguous. Please let me know if there is another way around.

Thank's
But do You Know what works with a direct assignment?

fft si complex number
E.g.fft = FFTSharp.Transform.FFT (real array)

FFTSharp.Transform.FFT is a .net assembly on the Fourrier transform

Thank you
