Incorrect heading results

[Dragonsigns]

Heading Indicator not returning same result. Heading Displays 30 Dec but my code returns 18 Dec.

double Heading = 0;

double Variation = 0;

result = fsuipc.FSUIPC_Read(0x0580, 4, ref token, ref dwResult);

result = fsuipc.FSUIPC_Process(ref dwResult);

result = fsuipc.FSUIPC_Get(ref token, ref dwResult);

Heading = dwResult;

result = fsuipc.FSUIPC_Read(0x02A0, 4, ref token, ref dwResult);

result = fsuipc.FSUIPC_Process(ref dwResult);

result = fsuipc.FSUIPC_Get(ref token, ref dwResult);

Variation = dwResult;

Heading = Heading * 360 / (65536.0 * 65536.0);

Variation = Heading - (Variation * 360 / 65536.0);

if (Variation < 0)

{

Variation += 360;

}

else if (Variation > 360)

{

Variation -= 360;

}

textBox11.Text = String.Format("{0:#}", Variation) + " Dec";

You posted this twice. I responded to the first one I saw.
