What is the procedure to find out the IDFT using FFT?

[SherlockBenedict]

I have searched everywhere but I couldn't find out the procedure to find out the IDFT using FFT. Can you plz refer me to some link or tell me how it is done?

Thanks a lot.

IFFT(X) = 1/N conj(FFT(conj(X))

where N ís the signal's length, and conj is the complex conjugate.

Well, I have assumed that IDFT = Inverse Discrete Fourier Transform, and that the algorithm to solve it is IFFT, the Inverse Fast Fourier Transform. Is that OK?
