CCS/CC430F6137: Read ADC output value using IQmathlibrary

Part Number: CC430F6137

Tool/software: Code Composer Studio

Sir, I try to read adc output value using IQmathlibrary but that value is not correct. how to read adc output value using IQmathlibrary?

here attached model code. 

int main(void)
{
 _iq1 A0results,A1results,index=0;
 float Iamps,Volt,Power=0,RMS_Current=0,RMS_Voltage=0;
 char res[12],res1[12];

WDTCTL = WDTPW+WDTHOLD; // Stop watchdog timer

P1DIR |= 0x01;
uart_init();

P2SEL = 0x0F; // Enable A/D channel inputs

ADC12CTL0 = ADC12ON+ADC12MSC+ADC12SHT0_8; // Turn on ADC12_A, extend sampling time
// to avoid overflow of results
ADC12CTL1 = ADC12SHP+ADC12CONSEQ_3; //3 // Use sampling timer, repeated sequence
ADC12MCTL0 = ADC12INCH_0; // ref+=AVcc, channel = A0
ADC12MCTL1 = ADC12INCH_1; // ref+=AVcc, channel = A1
ADC12MCTL2 = ADC12INCH_2+ADC12EOS; // ref+=AVcc, channel = A2
// ADC12MCTL3 = ADC12INCH_3+ADC12EOS; // ref+=AVcc, channel = A3, end seq.
ADC12IE = 0x04; // Enable ADC12IFG.3
ADC12CTL0 |= ADC12ENC; // Enable conversions

while(1)
{

ADC12CTL0 |= ADC12SC; // Start conversion

 while(!(ADC12IFG2));
A0results =ADC12MEM1;
A1results  = ADC12MEM2;

Iamps = _IQ1toF(A0results);
Volt = _IQ1toF(A1results);
uart_tx(0x0d); uart_tx(0x0a);
// Iamps = A0results;
uart_str("I:");_IQ1toa(res, "%2.4f", Iamps); uart_str(res);
uart_str("V:");_IQ1toa(res1, "%2.4f", Volt); uart_str(res1);

}

}
