Question: FFT range for a signal

I have a  signal from which I want to find the dominant frequency.   Does fft ignore the part which is constant (like DC)? Does that part affect the fft calculations?

    fft() does not ignore the DC component. The DC component is returned as the very first vector entry of the result.
