Using numpy.fft to calculate the multiplication of 2 numbers

Question

Is it possible to use numpy.fft to calculate the multiplication of 2 numbers in python? I know that the simplest way is just a*b , however is it possible to use numpy.fft as a way to calculate it? If yes, is there any sample of the code?

Answer 1

Not in a way that is commonly referred to when one states that you can use the FFT to multiply numbers. That refers to the Schönhage–Strassen algorithm , which uses the number-theoretic discrete Fourier transform , which is distinct from the FFT implemented in numpy.
