What is the conversion equation IQ24

Part Number: C2000WARE

Tool/software:

My colleagues shared his code, how he convert the hex value we poll from the device and convert into an actual value.

Below is the code he send me, but I'm using a different programming language called LabVIEW, so if any help can be provided I would be appreciated.

//----------------------------------------------------------

// From the TI library header file:

// Pretty sure that _iq equates to _iq24 in our usage

typedef   long    _iq;

typedef   long    _iq24;

//--------------------------------------------

// From the 9012

// The values are pulled from this structure

struct CommsDetType

{

    _iq iqTxAmplitude;

    _iq iqNaAmplitude;

    _iq iqFrequencyEstimate;

    _iq iqHitThreshold;

    // noise tracking

    _iq TxMean;

    _iq NaMean;

};

    // Psuedo code

    for (coil = 0; coil < 2; coil++)

    {

        for (phase = 0; phase < 3; phase++)

        {

            TxMean;

            pPkt += 4;

            NaMean;     //NA = Noise Average

            pPkt += 4;

            iqHitThreshold;

            pPkt += 4;

            iqTxAmplitude;

            pPkt += 4;

            iqNaAmplitude;

            pPkt += 4;

        }

    }

Basically,

this will all result a 47 dB, so I would like to know how the conversion is done from the hex to q value.
