Tīmeklisfloating-point. For the forward FFT (time -> freq), fixed scaling is performed to prevent arithmetic overflow, and to map a 0dB sine/cosine wave (i.e. amplitude = 32767) to two -6dB freq coefficients. The return value is always 0. For the inverse FFT (freq -> time), fixed scaling cannot be done, as two 0dB coefficients would sum to a peak amplitude http://fft.szie.hu/fizika/felevek/aktualis.htm paying tfl congestion charge
