complex discrete fourier Transform

I'm looking for the complex discrete fourier Transform of this EQ
impulse response array. I know the output for the first 3 values:
EQ.DFT MAG(floating)) should be 1.066769, 1.040460, 1.063209....
EQ. DFT MAG(Db) .561411,.344507,.532374....
CH Resp mag(dB) -.608192, .845447,2.019220....

I can for the life me not get this to balance against the returns
below. Any help would be greatly appreciated?

Dim real(23) As Double
Dim img(23) As Double
real(0) = 0.004395
