MATLAB: IFFT operation on the vector

MATLAB

Hello,
I want to make an ifft operation on some vector. according to help of ifft, it do not require any multipcation constant. does this statement true all the time?

As long as you do not zero pad, you should get back the original vector without using any scaling factor.
   x = randn(10,1);
   xdft = fft(x);
   y = ifft(xdft);
   max(abs(x-y))
