Fixed-point multiplication with "altmult_complex" megafunction

Hi, I am using the altmult_complex (complex multiplier) with inputs dataa (both real and imaginary) having 16 fractional bits, and inputs datab (both real and imaginary) having 2 decimal bits a...

Thank you very much for numerically detailing out my post/question.
