請問如下程序AD轉(zhuǎn)換值怎樣分離個位十位百小數(shù)位謝謝！

float voltage = 0.0; 
//uint V;
float VCC = 4.99;

//======== AD轉(zhuǎn)換程序 ======================================
uint ADC(uchar Od) 
 {
 uint AD_Result_Temp = 0 ;
 ADC_CONTR = ADC_CONTR|0x80; //1000,0000打開A/D轉(zhuǎn)換電源
   P1ASF = SET_IO[Od];//
   delayms(20); //20   
   ADC_CONTR = ADC_CONTR & 0xE0; //1110,0000 清ADC_FLAG,ADC_START位和低3位
   ADC_CONTR = ADC_CONTR|((ADC_ID[Od])& 0x07); //設(shè)置當前通道號00000111
   delayms(1); //延時使輸入電壓達到穩(wěn)定
   ADC_RES = 0; //STC12C5A16AD系列單片機_清A/D轉(zhuǎn)換結(jié)果寄存器高八位
   ADC_RESL = 0; //STC12C5A16AD系列單片機_清A/D轉(zhuǎn)換結(jié)果寄存器低二位
   ADC_CONTR = ADC_CONTR|0x08; //0000，1000ADCS ＝ 1，啟動轉(zhuǎn)換
   do { ; }    
   while((ADC_CONTR & 0x10)==0);     //0001,0000等待A/D轉(zhuǎn)換結(jié)束
   ADC_CONTR = ADC_CONTR&0xE7; //1110,0111清ADC_FLAG位，停止A/D轉(zhuǎn)換
   AD_Result_Temp = ((AD_Result_Temp|ADC_RES)<<2)|(ADC_RESL&0x03);//高八位+低二位
  return AD_Result_Temp;//ADC_RES;
 } 
//====檢測============================================
void PIS1()  //0.6V~0.8V   0.7V +_ 0.1V
 {
  //VCC = 2.499 * 1024 / ADC(0); //先讀取基準電壓算出供電電壓
  voltage = ADC(1) * VCC / 1024;
   } 

如果要將voltage 這個值用lcd顯示出來應(yīng)該怎樣分離個位十位百。小數(shù)位呢？謝謝！

你這個是adc0804?

stc12c5a16ad

voltage本身是個浮點數(shù)請問怎樣分離？謝謝！

這是我的溫度數(shù)值轉(zhuǎn)換，你看看
