Module real_u64 

Functions

fft2_real

Real 2-FFT over u64 integers.

fft4_real

Real 4-FFT over u64 integers.

ifft2_real_unreduced

Real 2-iFFT over u64 integers. Division by two to complete the inverse FFT is expected to be performed outside of this function.

ifft4_real_unreduced

Real 4-iFFT over u64 integers. Division by four to complete the inverse FFT is expected to be performed outside of this function.
