想通过280049实时计算一个非常复杂的公式，但是将该公式输入后发现出现如下错误
inline void pfcControlCode(void)
{//GpioDataRegs.GPASET.bit.GPIO0=1;a = L*vBus_in_volts;b = ac_vol_in_volts * vBus_in_volts;c = guiIi * L * vBus_in_volts;//Vin<0.5Voute = guiIi*guiIi*L*vBus_in_volts-4.0f*guiIi*Td*ac_vol_in_volts*ac_vol_in_volts+4.0f*guiIi*Td*b-4.0f*qoss*b+4.0f*qoss*vBus_in_volts*vBus_in_volts;//Vin>0.5Vouth = sqrt(L*qoss*(2*ac_vol_in_volts-vBus_in_volts));g = guiIi*guiIi*a+2.0f*guiIi*ac_vol_in_volts*(SQR*h-2.0f*Td*(ac_vol_in_volts - vBus_in_volts))+4.0f*qoss*ac_vol_in_volts*ac_vol_in_volts;if(ac_vol_in_volts > 0.5f *vBus_in_volts){f = d2*b/(sqrt(a*g)+c);}else{f = d2*b/(sqrt(a*e)+c);}perid=100000/f;//重新计算周期寄存器值EPWM_setTimeBasePeriod(EPWM2_BASE,perid);//EPWM1频率设置*///GpioDataRegs.GPACLEAR.bit.GPIO0=1;

这是为啥呢？是因为数据类型或者数据精度问题吗？
Green Deng：
你这个应该是警告，不是报错？
意思是coff格式下的工程建议用32位的精度来进行编程，你的程序中是定义了64位的双精度数据吗？
,
DSP应用：
0049不可以定义64位数据吗？
,
C YG：
可以的
,
DSP应用：
abc我定义的double，就会报这个错误，需要改哪里？
,
C YG：
你的数据很大吗？为什么要定义double类型，你这个需要检查，保证你的数据类型都是一样的，如果使用double建议将所有的都改成double试试
